Another Mercedes Renntech SL74, really?
We have seen three of these Renntech SL74 beasts show up for sale this summer, which is pretty unbelievable. Our previous finds:

Sometimes an owner will see another seller claiming to have a really are car and take the opportunity to show of his own to show the other guy he isn’t the only one. Sometimes following up one rare listing with another lets a seller piggy back on some of the excitement or the initial sale or lets them judge interest or gauge market value. Perhaps that’s the case with this third SL74.
This one is a 1996 in white found by reader Nik. It is a bit more showy than the other two we saw this year. Chromed intakes, vented hood, embroidered logo headrests, big sound system in the trunk, etc. The specs are right inline with the other two we’ve seen. The seller quotes an investment of over $200,000 and lists the upgrades as follows:
Specs:
V12 engine producing 595 BHP, 605 lbs-ft @4000 RPM. 0-60 is second 3.9 seconds and a top speed of 200 MPH 1/4 times of 11.9

With a day left this one is up to just under $17,000 reserve not met. The Buy-It-Now price is $28,900. As with the others I’ll say this again, that is a heck of a lot of depreciation. Unlike the others though this one has actually seen substantial use at 91,000 miles. That’s nice to see.

1994 Mercedes Benz SL74 Renntech
Today hearing of a Mercedes pushing 500 horsepower, while not really yawn factor, is certainly not surprising. AMG has done an amazing job generating massive power and torque numbers for Mercedes that you can now buy of the regular dealer showroom floor. While big engine big power Benzs have been a hallmark of the company for years they were scarcer in years past.
This big fellow could scare off just about everything else on the road when it was new back in 1994. The SL74 was a Renntech package that took the already potent Mercedes 6 liter V-12 and pushed it out to 7.4 liters. With about 600 horsepower and 600 lb. ft. of torque after the conversion all coming out of a lagless normally aspirated engine one could easily spin the z rated tires down to the rims.
It isn’t clear if this car was converted by Renntech just after the purchase or if the conversion took place later in the car’s life. With only 15,000 miles it doesn’t really matter.
This car has similar specs to the Renntech SL74 I posted early this summer:
http://germancarsforsaleblog.com/1997-mercedes-sl74-renntech-monster
Giant brakes (seriously look inside the wheels at those things), exhaust, limited slip diff, upgraded transmission all are necessary additions. The sort of things you would associate with a handbuilt rocketship. What sets this one apart, ironically, is at first glance it is so subdued. You could easily mistake this for just another R129 series Benz. The wheels are nothing too exciting, though closer inspection reveals them to be light magnesium wheels. Nothing seems too fancy about the bodykit, some flares and vents, not even a badge on the back, then you realize it is all carbon fiber, hood, fenders, rockers. This saves, according to the seller 600 lbs in weight.
A peak inside and you can see that this SL is not for prowling a Florida retirement community, though grandpa would probably like the feel of those Recaro ortho sport seats, grandma likely would not want to fumble with the four point race harness.
I believe you can still get this conversion done by Renntech if you have the cash. The original cost was $325,000, that included $110,000 for the stock SL600. Take the depreciation and buy this two owner sneak attack machine for $65,000. Geniuses drive green cars after all right? Hard top and stand included. Just be careful the seller has no feedback.
It is worth noting that the Renntech 7.4 should not be confused with the similar era Mercedes AMG SL73, which was a factory produced vehicle available in very limited numbers. The 7.3 liter AMG engine is the engine that went on to more recent fame as the power plant for the Pagani Zonda producing similar power figures as this Renntech.

1997 Mercedes SL74 Renntech Monster 17k miles
While Mercedes and its associated high end tuners went through a stage recently of getting huge horsepower numbers from supercharged and turbo cars, there is something to be said for pure normally aspirated big block power. This Renntech modified SL74 epitomizes that philosophy. The stock 6.0 liter 48 valve V-12 engine has been bumped out to 452 cubic inches and is generating 575 horsepower and 600 lb. ft. of torque. The power is mated to a five speed automatic that has been beefed up to handle the power. Worked over intake, uprated suspension and cooling systems, 14″ Alcon brakes, 18” OZ Racing wheels( 18” x 11.5” out back), and AMG bodyparts. Plus you get all the luxury interior components you would expect from a top of the line Benz of that era. The seller says he whole package cost $90,000 from Renntech when it was new.
All that huge no lag power must be an real blast. The car is hardly broken in with only 17,000 miles. The car looks like it came from Canada since I see Manitoba plates in one of the photos. For $79,000 you can go pick this car up in Dallas Texas and have a fun comfortable ride home anywhere in the country.

2005 MINI Cooper S with RennTech Supercharger
The MINI Cooper has been hailed as one of the most fun and best handling cars for the money but many owners have been left wanting more oomph out of the tiny 4-banger. While I haven’t driven the JCW, I can imagine it offers a good bump in performance. An alternative to these straight-from-MINI upgrades is a RennTech package, which doesn’t quite make sense seeing that MINI is a BMW brand and RennTech is a Mercedes tuner…
Anyway, the RennTech package, which I couldn’t find any information on, consists of a RennTech Supercharger with larger Pulley and Air Intercooler. In addition, this Mini received a Race Short Shifter, Pagid Brake Pads with Red Calipers, Borla Exhaust and powder-coated 17’s which adds up to roughly $10K in upgrades.
This Cooper also carries the added significance of being owned and driven by Bob Snodgrass (1942-2007), President of Brumos Racing. The auction says Bob specifically made this car for himself and described it as “truly like driving a Porsche”.
With low miles, nice upgrades and the status of the previous owner, I doubt that this Cooper will get away for a MINI price…sorry it was just too easy.

RENNtech Mercedes-Benz 500E Sleeper
“Performance without Compromise” – This is the motto of Florida-based Mercedes-Benz tuner, RENNtech. Started by Hartmut Feyhl in 1989, RENNtech is known as one of the leading authorities for performance modifications for Mercedes-Benz AMG models. Feyhl gained a great amount of experience and expertise over his 12 years as the North American technical director at AMG. He was also heavily involved in the “AMG Hammer” project.
This brings us to our featured auction, a 1992 Mercedes-Benz 500E with RENNtech modifications. Hand build in co-operation with Porsche, the 500E was known as the “wolf in sheep’s clothing”. In this example, the already beefed up dual camshaft 32-valve, 322 hp V8 gets an updated ECU chip, rear exhaust, carbon fiber airbox that the owner says is good for an additional 45hp. You can imagine that this will shave some time off the already impressive performance figures: 0-60 mph in 5.5 to 6.0 seconds, quarter-mile in 14.1 seconds at 101 mph. The top speed was limited at 155 mph…but my guess is that the ECU chip removes that governor.
Here are my two gripes with the car. First is the mileage. I know Mercedes builds solid cars and bulletproof engines but 150,000 miles is a significant amount for a tuned V8, especially if you’re going to drive it like a sports car. Second, I don’t think beige has any place being on a sports sedan, especially the exterior. Luckily the trunk needs to be repainted, so why not do yourself a favor and paint the whole car black, the color it should have been from the factory. Besides those two points, I think this is a great opportunity to own a rare Mercedes classic at a reasonable price.

Mercedes 560 SEC Coupes, 6.0 AMG
Being a Mercedes guy, I’ve always liked the 560sec and its siblings of the same body style. Here are several all up right now on eBay.
The body on this one has 292,390, but it has only 50,000 since a full restoration. The ad doesn’t say much about the 6.0, but the valve covers look genuine. Seller says all the documentation from Renntech is available. Pretty subtle for having an AMG engine, transmission, headers and rear end.
Here we go, this is a GREAT opportunity. Rarely do you find a decent vehicles listed on eBay at a low opening bid AND no reserve. A 55,000 mile 560 that looks amazing up for sale with the public setting the market price. This is fantastic if it was a standard 560 SEC, but this is a grey market car with an AMG body package. So you get the nice Euro headlights and the sculpted bodywork. Don’t miss getting a bid in on this one, someone could snag a real deal if this one goes under the radar on eBay. Probably not the smartest move for me to post this here since I’ll probably throw a bid in on this myself, but I’d like to see what the market sets itself at. If this was a later model, year I’d say if it didn’t breach $10k it would be undersold.
Here is a white one that the seller claims is a multiple show winner. I’m sure it is nice, but a 100,000 mile, 1991 model year car, in stock form must not have much competition in its class at whatever shows he’s entering it in. The car does look good and is nice that it has service records, but you can almost be sure that the ask for the car is going to be over priced just by the way the seller is describing it.
I just put this one in because I always find older 1 owner cars intriguing. Being the 2nd owner on a vehicle that has a long history with its original owner can mean some neat stories and a chance to really know the car’s past. This 160k mile car is a California delivery vehicle so a buyer is going to want to look out for extra smog gear restricting the engine.
And this is for the handyman looking for a bit of a challenge. Chances are you can talk the owner down from the $1875 ask. Sadly I think you’d have to go down on price to find a taker, but then you get close to part it out territory as the parts become worth more off the car. Who wants to save this one?

1987 Mercedes 300 Wagon with AMG 6.0 litre twin cam motor
-->
There are several Mercedes 300 Wagons in our neighborhood. I often think that if I had one I’d want to lower it an inch, put on period AMG monoblock rims, color match the lower panels, and upgrade to European spec headlights — which would make for a great family ride.
But this 300 wagon takes it to another level. It has the AMG 6L motor, 3 piece rims, and very rare body kit, to name a few of the tasteful and rare upgrades. Here is the majority of the seller’s listing from the eBay ad for this 300 AMG Wagon:
