Self-Serve Special – 1984 BMW M635CSi

To round up what has been an excellent week for the S38 motor here at GCFSB, I thought we’d take a look at the Euro version of this car. The M88 is a legendary motor for BMW; powering the M1, it was slightly modified with Motronic fuel injection for the M5 and M635 – where, amazingly, it produced more power than the M1 had. For a long time discarded in favor of the later M6 on U.S. shores, the grey market examples of the M635CSi offer a better power to weight ratio and cleaner European styling. Optional were then-giant 415MM TRX BBS Wheels, along with the requisite Euro-market wipers. Awesome? You bet, and one has popped up on our self-service classifieds:

CLICK FOR DETAILS: 1984 BMW M635CSI on GCFSB Self-Serve Classifieds

I have owned this beautiful graphite gray metallic Euro M635csi with 70,318 miles on the clock since 2004. It is optioned with black leather interior, rear-fog lights, and the headlamp wash-wipe system. This BMW has its original 415MM BBS wheels (that do not leak). The recall on these three-piece BBS rims came on wheels installed on M635csis, built after this car was built, as this one was the 248th assembled. It has the M88 motor in European tune with the dual valve job, Frank Fahey nut, and header in place. The car has an Alpine CD stereo installed now, but I do have the original Blaupunkt radio-casette player. I have an extra stripe kit, car cover, EPA & DOT paperwork, and all maintenance records from myself and the previous owner. This M635 is in all original stock condition that has never been modified, molested or raced. I have enjoyed the car for 10 years, never been driven in the rain or snow and always garage kept. Yet it is a toy and not a daily driver and I am starting to downsize with the intention of moving, therefore, I have decided to sell the BMW.

If you’re looking for a clean, investment-grade 1980s M car, this is a great way to go. It’s clean enough to keep as is and maintain, while not so low-mile that you’d worry about adding to the total. I’d probably grab a set of Style 5 17″ wheels to maintain the look while protecting those expensive TRX tires for show or resale; otherwise, you’re looking at $2,000 plus worth of tires. Outside that, with all the records in place, in a pleasing color combination and for a reasonable market price, this car is a great option to quench your 80’s thirst.

    Looks like a very nice M635. It is rare to find these cars with <100k miles so this would qualify as a low mile car IMO. The Recaro seats are a rare option although there is no real benefit to them compared to the stock sport seats. The car had front and rear turn signal repeaters installed during federalization; most cars got away with rear lights only. I think this is a very fair price and in 10 years it will be looked back on as a bargain.
