10K Friday: Big Coupe Off – 560 SEC v. 633 CSi v. 928

Today we’re going to have a slightly different flavor for 10K Friday – big coupes. All three of today’s cars represented the peak of their respective brands when they were new and all three have achieved cult followings and collector status. Yet all three do their jobs in very different ways. We’ve got a last of the breed 1991 Mercedes-Benz 560 SEC, a beginning of the run European-model Porsche 928 5 speed, and a middle of the run E28 switch-over 1983 BMW 633 CSi. Which would be your Coupe du Jour? Let’s start with the Mercedes-Benz:

This car certainly looks pretty clean in the photos, and miles are right about where you’d want them. Price seems to be really great for the condition and claimed “museum quality” status. While that may be an exaggeration, the car does appear well kept. In out last executive sedan shootout, the Mercedes-Benz 560 SEL was pretty soundly defeated by the newer Audi S8 and BMW 740i; but in this case, the 560 is the newest of the three and in the best condition. I love the pillar-less design of these coupes, black is an appropriate color (though probably not what I would have chosen) and aside from the radio, it appears all original. It sure looks like a lot of car for your coin – but will this “German Corvette” sway your decision?

The early 928s, like the early 6 series, are the cleanest of the designs, especially in Euro-trim. While they’re not the most aggressive looking, it’s amazing how fresh the design still looks now 35 years later. This particular model is one of the better ones to look at for enthusiasts, with a 5 speed, red exterior and that crazy psychedelic interior:

While it sounds like it needs a mechanical freshening, the condition this car is presented in is impressive and the miles look believable. If you want an early 928 that would be collector status, I think this one fits the bill perfectly. The 5 speed coupled with the European motor gave a lot more motivation than the U.S. market saw until the end of the run. Yes, it has needs, but I feel the price appropriately reflects those needs and this one surely is the looker of the group. But if Porsche repair bills are a little too scary for you to contemplate, how about this BMW?

The 6 series is on an upward tick in value, following the steadily appreciating E30 and newly rising E28 models. While I think the early Euro-cars are the best looking of the run, without a doubt the best drivers are the later E28-derived models such as this one. White over blue probably wouldn’t be everyone’s first choice, but this car is presented as an all-original 1 owner car:

Up for Sale is My 1983 BMW 633CSI in factory original Alpine White paint with original Pacific Blue leather interior. This car is a true survivor and is all original, no accidents or damage EVER. This is an estate 1 prior owner California Car. This car has no rust, no re-spray and factory original under coating. Perfect under carriage. I bought this car from a car broker that got it from the estate. I have a copy of the original California title and original California plates. Along with the car comes the original books and cassette cleaning kit (cool). Factory tool set intact but missing a pliers. You can get in this car and drive antwhere…..

This car is an amazing RARE Alpine White over Pacific Blue 5 Speed California Model. Up until now the car has been off the road since 2005. Appears it would not pass smog and was garaged. I have gone through this car and it is back on the road and running great. I have spent dozens of hours and over $3000 in parts/service alone in the past 60 days. Receipts included. Car is now smog and odometer exempt in most states. Please check your states DMV for its laws.

Here is a list of the items serviced and repaired in the past 60 days.

The car starts right up and runs very smooth. No smoke or leaky valve guides. Very strong engine and trans and shifts very smooth. Car drives tight and handles very well. These cars are the European muscle cars of the 80’s only way more smooth and solid. The original Alpine White paint is in excellent original condition with only a few minor dings. No rust or peeling of any kind. All trim in good shape. Factory matched basket wheels are in great shape. Factory under coating intact and no issues under the car. Power sunroof works great. Power windows go up and down. Cabin heats well and blower fans work. Dash has a few cracks from the California sun and has a dash mat in place. Door panels are excellent as well as carpet.

Here is what I feel still needs to be serviced at some point in the near future.

Front end alignment
New muffler
New tires
AC service
New rear speaker pods
Repair driver seat leather

Dye interior all back to deep rich Pacific Blue
Buff and wax

This car is a great investment and will only go up in value in the very near future. You just don’t see time capsuls like this very often. I wish I could keep the car but I have to many projects going right now and don’t have the space.

So unlike the 928, lots of service to get it back running, but also some time needed to finish sorting the details. For me, the mid-range 6s in the 1980s are the least appealing of the run, but they’re nice drivers, pretty reliable and long lived, and certainly will appreciate if maintained over the coming years. Though this car looks rough in the photos, I think with some time and attention the exterior would really sharpen up quite a bit, though the interior also needs attention. As with the 928, the price in part reflects the need for work, though while I think the 928 price is more or less spot-on, I think this price may be a little high still considering the work needed, overall condition and miles on the car.

Were it my money, it’s down to the Mercedes and Porsche. The 560 looks pretty immaculate, especially considering the price. The logical side of me says “STAY AWAY” from the 928, but I love the color combination, the interior, the manual transmission, and European build. Those details would just be too much for me to overcome and enough to push the better Angel off my shoulder.

Which would you choose?

    The first Porsche I ever drove was a 1978 928 5 speed. That was enough to make me a fan for life because it was just on another level compared to my (then brand new) 1985 Trans Am. However, the maintenance costs even then were frightening.

    My dad bought a brand new 1984 733i in December of ’83. He had also test driven (with 14 year old me as a passenger) the 633CSi. Despite the drop dead looks of the 6’er, he went with the 7 for practicality reasons. The next year we went to test drive the newly arrived 635CSi and that felt like a totally different animal. So if this white one were a 3.5 liter model I might be swayed by it.

    Now comes the 560SEC. Truly one of the all time greats, especially back in the day. Quality, workmanship and that solid bank vault feel put it head and shoulders above the 928 and the 633. It would be my choice today.

    I don’t even know what to say about the seats in that 928. Fabulous. Ridiculous. Listing has ended in any case. The 560SEC has always had my attention for that perfect blend of sport and luxury, swagger and solidity. I’d feel like a yakuza boss cruising in that thing. Has my vote.

    The 928 must have sold locally (as described in listing) because the auction was due to go through the weekend. Sorry about that!

    Although I like them all (including the Pascha interior of the 928), I’d choose the 560SEC in this case. It appears to be in better condition; it is the last of the run which usually means all of the bugs are worked out; and it is from a time when Mercedes really built some solid cars.

    There was a reason a lot of GP pilots drove SECs back in the day. There is an elderly lady who lives on my street who still drives her white 560 SEC.

    I bought the ’78 928, so my vote is obvious. 🙂
    It’s a really nice car inside and out, and needs a good mechanical going over.
    My favorite thing about the car is it’s striking color combo.
    I’m going to perform a ‘driver’ resto on it and put it back up on the market.
