1985 BMW M635CSi

The M635CSi somehow gets lost among the other greats of the period from BMW. Perhaps, for U.S. fans, it’s the nomenclature that’s confusing. After all, there was a M1, an M3, and a M5, but when it came to the M version of the E24, BMW stuck with the moniker M635CSi in all markets but the United States and Japan. Confounding that decision was the launch of the E28 M535i. Like the M635CSi, it had additional body pieces, special interior trim and wheels from M-Technic. But while the M535i had a fairly normal M30 under the hood, the E24 received the full-fat M88/3 that was shared with the M5. Like the European M5 production started in 1984, well before they were available to U.S. customers. But while the M5 only sold in very sparse numbers over its short production cycle (about 775 sold in Europe between 1984 and 1987), the M635i was a relative hit, with just over 3,900 selling overall – far more than made it the U.S. market. Additionally, the European models were a slightly more pure form of the design; smaller bumpers, less weight, and about 30 more horsepower on tap without catalyst.

These European spec models were offered with some color combinations and interiors that never came to the U.S. market. This one is quite rare to find in Bahama Beige Metallic with Buffalo leather:


Year: 1985
Model: M635CSi
Engine: 3.5 liter inline-6
Transmission: 5-speed manual
Mileage: 132,300 mi (TMU)
Location: Miami, Florida
Price: $46,900 Buy It Now

Available now this very early E24 Euro Spec M6, powered by the legendary M88 inline six, which is the same powerplant as the iconic M1.

Ordered and purchased new at the BMW Factory through the BMW dealer in Stuttgart by its original owner while stationed with the Armed Forces in Germany, subsequently, he bought the car home with him to Virginia, keeping and maintaining regularly until April of this year.

The available original purchase Bill of Sale and documents from April of 1985 specify the order in rare Bahama Beige Metallic over Natural Buffalo leather and a total price paid of 97,900 Deutschmarks (About 49,000 USD). Optional factory equipment includes Anti-theft system, Green Heat Protective Glass, Air Conditioning, Stand Heater, Becker Mexico Radio, Sunroof, and Automatic Antenna.

Together with the purchase documents, original brochures and pricelists were kept and come with the document stack.

During its tenure in Germany, this pride and joy car was dealer maintained and serviced in Stuttgart and Nuerenberg, all for which original paperwork is available. After arriving in the US and imported by the same owner, the car was kept up with meticulous service and periodic maintenance, for which every single receipt was kept. Receipts show a big service including timing chain and guides performed at 122K miles.

The Eurospec body looks amazing with its smaller bumpers, wider arches and original BBS wheels wrapped on Period Michelin tires. The Bahama Beige Metallic over the Buffalo Natural Leather add to a very attractive continental look that gives this car a great curb appeal. While driving, you can also tell the difference between a US and a Euro Spec with a much less restrictive exhaust, and an engine with 31 HP more, thanks to not having the restrictive supplement air pump. Autobahn designed gear ratio also provide the Euro car with a much higher top end speed and cruise.

Body is straight all around, and it is accident and rust free, paint shows a bit of weathering on the clear coat but the overall looks great for the age. Buffalo Leather interior looks amazing and ads an incredible amount of personality to this great car.

The color looks a lot like the similar Bronzit, but Bahama Beige is much rarer because it was only offered on early models in Europe. Inside is cool Buffalo leather that also wasn’t found here, and of course you have the more slim Euro bumpers. It’s nice to see that the car retains its TRX wheels from a purist point, but tires are pretty expensive for them and limited to only a few choices. The car looks to have had some paintwork and was perhaps Federalized based on the MPH speedometer, but it’s still a great-looking classic that has more-than-adequate power and is very rare to find today in the US. As I eluded to before the break, despite that these remain relatively affordable – $47,000 is hardly cheap, but it’s roughly on par with what other examples sell for – and when you compare it to what similar 911s would sell for…

    Bahama Beige was available in the US, at least in the E23. My dad almost bought a new 733i in 1984 in Bahama Beige but ended up with a Bronzit 733i instead because he got a better deal from another dealer.

    I prefer the M635 far more than the M6. Not only do they have roughly 30 more hp (due to higher compression ratio, tubular headers among other things) they are 300 lbs lighter so the power to weight ratio is 15% better. This car looks like it has had paint work as the driver’s side panels do not all match, and the buffalo leather has faded like they all do. Also the dealer is in Miami so , as always, buyer beware. The biggest concern is the TMU and health of the M88/3. These euro engines need top end/timing chain work at or prior to 100k miles. If this car still has it’s original single row timing chain and components it will need to be done. A rebuild of one of these heads with timing chain is very costly so a review of service history AND a leakdown test is mandatory. If all checks out the price is not unreasonable.

    These are US M6 wheels. The original M635 wheels are gorgeous 3 piece BBS wheels, also TRX.

    @Greg the three-piece TRX RSs were optional on the M635CSi. These are the correct wheels I’m pretty sure.

    @Ed – Interesting! But it wasn’t available on the M6 here, as that came after the color was discontinued.
