1977 Mercedes-Benz 450SLC 4-speed manual

When the R107 Mercedes-Benz SL debuted in the early 1970s, it was a decidedly more boulevardier cruiser than it’s Pagoda-roofed predecessor, the W113. Mercedes then decided to base their replacement for the W111 Coupe on the R107 chassis, resulting in the C107 SLC. This was the only Mercedes-Benz coupe to be based on a roadster, rather than the other way around, with exception of the SL65 AMG Black Series. With the extra ten inches in length and unique louvers in the rear quarter windows, there was no mistaking this larger SL variant. Most R107s and C107s that arrived on US shores came with automatic gearboxes. Those in other markets could specific a manual, mated in some cases to the the larger V8 engines. This 450SLC with the 4.5 liter V8 and 4-speed manual transmission is for sale in Missouri. It wears later style alloys, comes with the original set of bundt alloys and has covered a low amount of miles for its age.

Homologation Special: 1979 and 1980 Mercedes-Benz 450SLC 5.0s

It’s hard to believe it’s been over two years since Paul last wrote up a 450SLC 5.0, a homologation special intended to get a big motor into a lighter SLC to make it competitive in World Rally Championship. Remember, this is the pre-Quattro days, so a heavier rear driver wasn’t such a crazy proposition. It was aided by a fair amount of aluminum, too – the engine, doors, hood and trunk all were switched to aluminum. In the case of the hood – long enough to land a small aircraft on – that change made a difference. They didn’t sell like hotcakes though, and few remain today; they’re rare sights for sure, and it’s a treat to get two at the same time. Let’s start with the 1980:

1974 Mercedes-Benz 450SLC

I’ve always admired the Mercedes-Benz C107 SLC. It’s one of those cars that doesn’t get a lot of attention and as a result, has turned into an affordable classic. If you caught a glimpse from the front, you’d be mistaken to think this was another seventies or eighties era SL, but look a little more closely, and you’ll notice a windscreen that is a bit more vertical. Then take a walk around the side and the extra length and louvers in the rear quarter windows are readily apparent. The C107 and open roofed R107 SL sibling have been called some of the prettiest Mercedes-Benzes ever made.

This SLC for sale in Connecticut has been restored and has the euro spec headlamps and slim bumpers which add to the lithe appearance. But don’t be fooled by its grace. These are robust machines with plenty of power on tap.

Year: 1974

This classic Benz has been my personal vehicle for the past 19 years. It’s in amazing condition. About 3 years ago I had the body completely stripped and refinished in a stunning burgundy PPG metallic, and exceptional attention was paid to the detail as can be seen in the pictures. The interior was meticulously restored in the original colors and looks as good as it did when it came from the showroom. The bumpers and headlights were converted to the Euro style which restores the original classic look. Many mechanical upgrades have been made including a complete new exhaust system, brakes, new radial tires, Pertronix electronic ignition and fresh tune up, new battery and new water pump. All hoses, belts, fuel and brake lines and main sub frame bushings have been replaced. The A/C blows cold. It drives great and always gets plenty of compliments wherever I go. A beautiful example of these classic luxury sports coupes, which are just starting to take off in value.

Please call or email with questions at 860-463-8026, ebharris1@comcast.net. I also have many spare parts for 450SL/SLC’s. Thanks for looking!

Even though it’s a car hailing from the Northeastern US, the refresh has done wonders for this car. The color combination is very tasteful and doesn’t date the car in the way some of the other colors on offer at the time do. Around $15,000 to $20,000 can buy you the best 450SLC out there these days. Given the condition, long ownership and work done to this car, I’d suspect somewhere around $12,000 to $14,000 would be a realistic figure for this coupe.

1972 Mercedes 350SLC 4-speed

I’ve always liked the SLC model Benzs more than their removable top SL brothers and when it comes to the R107 and C107 chassis the 350SLC is one of the rarest of the breeds outside of the 450SLC 5.0/500SLC, which are significantly more scarce and the most expensive Benz you could buy at the time outside of the 600.

Year: 1972
Model: 350SLC
Engine: 3.5 liter V8
Transmission: 4-speed manual
Mileage: 105,756 miles
Price: Dealer, $9,950

1972 Mercedes-Benz 350SLC at Beverly Hills Motor Cars via Hemmings

1972 Mercedes 350SLC 3.5

The 350SLC contains one of Mercedes lesser known engines, despite it being the first major, high production volume V8 in Mercedes line up. (Though the M100 engine predates the M116, it wasn’t exactly a high volume engine when the M116 came out, just high displacement)  The high revving 3.5 liter V8 is often over shadowed by the more common 4.5 liter V8 of the same era. The smaller engine though is the more desirable of the two with the 3.5 liter being a compact powerplant that generated power in part by having a near 10:1 compression ratio, higher than the 4.5. With the 3.5’s high compression combined with earlier, non-emissions strangled production, it generated more power than the 4.5 as well. The 3.5 could put down a bit over 200 horses and was generating power at very strong horsepower per displacement ratio, there weren’t a whole lot of other regular road cars squeezing so much out of so little back then.

What sets the SLC apart from the SL is not that the hard top is simply fixed as many people mistakenly believe. The SLC is actually a bigger car and was designed as a 2+2. Compare an SL next to an SLC and you’ll see that the space between the door and rear wheel is noticeably longer on the SLC. As such the SLC is actually slightly heavier than SL.

Distinguishing between the 3.5 and the 4.5 can be tricky at first look since they are pretty similar. The 3.5 is a M116 engine and the 4.5 an M117. These engines are so similar that a trick for extra jump in your 4.5 is to take heads from a 3.5 and bolt them right on. This swap takes the 4.5s lower compression ratio and turns it up to 11 as in 11:1. The identification is also complicated by Mercedes breaking with the normally accurate, for the time, tradition of putting the badge on the lid that corresponded with the engine size. I say this because some U.S. market 350SLCs retained the 350 badging, but to meet emissions requirements had the less rare 4.5 under the hood. If you purchased a North American bound 350 series coupe or sedan it would come loaded with the 4.5 and you could be given an envelope with the correct 450 badging for the dealer to install if you wished, many cars never had the badges corrected so buyer beware if looking at a stateside 350.

A look at the tachometer is one way to see what you have. The 3.5 liter engine had a pretty crazy RPM red line of just under 7,000, again like its power to liter ratio, this sort of revving wasn’t seen too often from street V8s. The 4,5 SLs and SLCs will have red mark south of 6,000, while you can see on this car it is above. The seller mentions the higher red line in the post. The way the seller words the listing they suggest that there is something special about the engine that gives the car the higher redline, but I suspect what is meant is simply that the car has the 3.5 under the hood so the engine internals are probably stock, but having the 3.5 in a “U.S. spec” 1972 is unique.

The seller says this car was delivered special for Pan-Pacific Rally. The SLCs had a great rally career in some serious rallying events. The rally prepped cars that competed in the dirt and mud looked a bit different then the car here. I would like to see the documentation about what the seller means, was this car intended to compete, was it a press car, etc.. This car has been for sale before and generated similar questions from aficionados. It is interesting that this car is not equipped with A/C as that was standard fare for the SLC. A car delivered for a rally in parts of Mexico would have to be somewhat serious to not be fitted with A/C.

Without seeing the car in person from what I can tell the only thing special about the car is that it is an early stateside 350SLC with the 3.5. Of course it does come with a manual transmission, a 4 speed mated to a rev happy V8 will be fun. The manual in the 350SLC was not rare in the rest of the world, the auto was actually the option, but seeing any Benz with a manual in the states is generally thought of as at least slightly special and desirable. Give this car a performance exhaust to open it up a bit and it would provide your ears enjoyment as well.

This car is listed at a dealer at just under $10,000 with 105,000 miles. Not a spectacular deal if you are looking to land a 70s SLC or SL, but with the rarity of the 3.5 and 4 speed combo that ask isn’t out of line for dealer pricing (there is another dealer currently listing a Euro spec model with 180,000 on the clock for $14,900). The car also hasn’t been saddled with later ugly safety bumpers.

1978 Mercedes-Benz 450SLC

After the W111 coupe faded into the sunset in the early 1970s, Mercedes-Benz decided to replace the S class coupe with a new coupe based not on the new W116 S class sedan, but the smaller R107 roadster. With a stretched wheelbase and rear quarter windows with their distinctive louvers, this car had a lower, sportier stance than its predecessor, but it was still every inch a Mercedes touring coupe. Just under 63,000 SLCs were produced over a nine year time span, during which time they campaigned a 500SLC and won the 3,300 mile Bandama Rally in the Ivory Coast in 1980. This would be the last rally car to be campaigned officially by Mercedes-Benz.

Today, the SLC is a bit lesser known when it comes to classic Mercedes-Benzes, not sharing the same popularity as its open roofed sibling, the SL. But this obscurity does make for a more affordable classic. This 450SLC for sale in Philadelphia is a good driver quality vehicle and still looks sharp in basic black.

1978 Mercedes-Benz 450SLC on eBay

The mileage represented on this vehicle is accurate. This vehicle has a smooth shifting transmission. All power equipment is functioning properly. This is a smoke-free automobile. The engine on this vehicle is running properly. Overall, this vehicle’s exterior is clean. The interior is clean and in good condition. There is 50% of tire life left on this auto.

This car looks fairly straight on the outside, but the mismatched interior is a glaring fault. It appears as if the front upholstery was replaced, leaving the worn out leather on the back bench. This prompts me to question where other shortcuts were made in the care and upkeep of this vehicle. If in fact the mileage is correct and mechanically it is sound, I’d say it might be worth taking a flyer on this car. The Buy it Now price is not terribly high, but with the bit of freshening up the interior needs, along with other cosmetic issues like the rear window lamination failing, an offer of somewhere between $5,000 to $6,000 would represent a decent buy.

1979 Mercedes-Benz 450SLC 5.0

When the R107 SL replaced the W113 SL in 1972, many enthusiasts derided the new car as more boulevard cruiser than “sport light,” as the SL moniker suggests. Mercedes sought to bring back a little bit of the sporting magic in 1977 with the introduction of an all aluminium 5.0 liter V8 in the hardtop SLC variant. Dubbed the 450SLC 5.0, this model was different than the standard SLC models in that the hood and doors were aluminium, as well as the trunklid, which came with a black lip spoiler. These were very limited production cars, as 1,636 450SLC 5.0 were produced, along with 1,133 500SLCs manufactured in 1980 and 1981. These luxury touring cars were even campaigned on the World Rally Circuit, winning the Ivory Coast Rally in 1979 and 1980. This example for sale in California was an early build, and was imported to the US early in its life.

1979 Mercedes-Benz 450SLC 5.0 on eBay

Special, limited production cars are always exciting, more so when they are fast and have race or rally pedigrees. This 1979 Mercedes-Benz 450SLC 5.0 has all of that and more. A total production of this model is 1470, according to numerous sources, and the World Rally Championship history of the 450SLC 5.0 is well documented. This particular car #300, chassis number 107.026-12-000300 has all of the European specification horsepower, integrated bumpers, covered headlights etc, with NONE of the associated worldwide rust issues, due to early importation to California.

The car is equipped with 450SLC 5.0 specific front air dam and rear trunk spoiler. These aerodynamic aids were first used on this car and then subsequently carried over to the 1980 500SL/500SLC cars, and also later models. Beautiful Mercedes-Benz original alloy wheels remain in excellent condition, with tires that have substantial tread remaining. Brake and chassis maintenance are up to date, giving this car an extremely rewarding driving sensation. It is easily as fast as any SL/SLC we have owned, numbering in the hundreds. It definitely ranks in the top several cars owned/driven/tested for speed, agility, and overall driving feel.

The car was imported to California within the first year or so, as evidenced by it’s license plate nomenclature: this series of plates dates to approximately 1980. The condition of the car has some very important high points, including a rust free chassis and bodywork, as well as really beautiful original paint. The Euro velour interior is in 99% perfect condition, with only a thread or two showing at the absolutely highest wear point in the car: the seat bolster on the driver’s side–contacted every time one slides into the car.

Overall, the interior shows careful long term use with a perfect dashboard, above excellent wood, fully functioning gauges etc. The center of the rear seat has a bit of fraying on the strap (see photos), but that’s about it. The all important engine: up to date tuneup services, fluid maintenance, etc. The odometer reading of 83,000 + miles is accurate, and it all feels right. Alternator voltage, fuel pressure and various other parameters are all tested good. The car is ready to enjoy, right now. The previous long term care, the low miles, and our expert stewardship of the car will provide the next owner with a wonderful driving experience of a very limited production high performance car.

While these are rare cars, they aren’t the most high profile Mercedes-Benzes with collectors, so values have stayed rather reasonable to the point where ordinary enthusiasts can afford them. This is a good thing and a bad thing, as more people can enjoy the awesomeness of this car, but then, they may fall prey to less than careful owners. I’ve seen some SLC 5.0s sell as low as $6,000 to $8,000 in recent times, so if I had to peg a value on this car, it would probably be anywhere from $11,000 to $15,000 on the high side.

1991 Mercedes-Benz 560SEC with 52,000 miles

If Mercedes-Benz still made brand new W126 S class sedans, I think people would buy them, as their style and durability were hard to match as compared to cars that preceded and followed it. The C126 coupe based off the W126 chassis was the flagship of the line in the 1980s. While not as wildly popular as the longer lived R107 SL, this coupe blended understated pillarless coupe styling with the smooth M117 5.6 liter V8 and all the bells and whistles the discerning consumer could ask for. Low mileage R107 SL roadsters are rather easy to come across, but few C126 coupes remain in good shape. This 560SEC for sale in Oklahoma looks showroom fresh with just over 50,000 miles and is sure to delight as much as it did the day it rolled off the showroom floor.

1991 Mercedes-Benz 560SEC on eBay

This is a rare and truly original 560SEC. The last and best year for this model and one surely to become a collectible. This car has only 52,000 miles. It is a three owner car with all books and records including window sticker and various other documents. The paint is very good original condition with minor chips, no dents or dings. The interior is excellent, and the glass is original and in excellent condition. Everything works as it should including seat retractors and radio. This car is ready to go with no issues. They can be very costly if they are not well kept and this one has always been well maintained. There are not many black cars left in this condition with low miles.

Having been built in July 1991, this is one of the very last C126 coupes to have rolled off the production line. Everything about this car is right; the color, the miles, the year, you name it. I even think the asking price is reasonable given the immaculate presentation. This is yet another car I would love to call my own, if it were not for money and space limitations. Whoever winds up getting this car is not only getting a good bit of class and luxury for the price, but one of the best engineered big Benzes of our time.

1981 Mercedes-Benz 380SLC

Mercedes-Benz coupes have always been revered for their elegance, however, the SLC was an interesting beast. Based off the R107 SL, the chassis was stretched directly behind the door to create somewhat odd proportions. The 1981 model year represents the last year of the SLC, and the only year the 3.8 liter, all alloy V8 appeared in the coupe. Here is a clean example for sale in Florida.

The seller states:

This car has been well maintained and is in excellent condition. Full power everything. All working components and all original equipment. With only one previous owner, this automobile is ready for you. The mileage represented on this vehicle is accurate. This is a smoke-free automobile. There are no signs of prior damage on this vehicle. There is no damage evident on this vehicle. There are no noticeable dings on the exterior of this vehicle. This is a garage kept vehicle. This vehicle has a smooth shifting transmission. The engine on this vehicle is running properly. All power equipment is functioning properly. This vehicle has no known defects. The exterior of this vehicle is extra clean. Extra clean interior. Absolutely no rips, odors or abuse. There is approximately 75% of the tire tread remaining.

The price of clean R107 SLs is on the rise, but the SLC derivative is one of those obscure Mercedes models that proves to be a good value for savvy collectors. The asking price of $9,900 seems quite reasonable given the vehicle’s history and the fact that it comes from a sunny state. Sound investments are hard to come by these days, but this is one investment vehicle (literally) that you won’t lose your shirt on.
