1985 BMW M635CSi 5-speed Manual, Modified – Euro model

Up for auction is a 1985 BMW M635CSi, first retailed in Germany and imported to the U.S. in 1986.  It remained in Georgia and Florida until 2010 – when it was imported to Canada by the seller with approximately 120,000 km on the clock.  The M635CSi is a model which was not available new in North America; BMW uses the “M” designation for specially modified higher trim model, indicating its Motorsport division – thus, M635CSi.  A European model E24 (internal BMW body designation), its engine is the BMW M88/3 – a direct descendant of and more powerful than the M88 that was used in the vaunted BMW M1.  Its performance also far exceeds that of the 1985 North American market 635CSi (no “M”) – the car available in our auction was rated at 282 horsepower when new, compared to 218 horsepower for the domestic 635CSi.  More details are available below but this car is modified and horsepower today exceeds that original 282 rating.  Cosmetically, the wraparound bumpers on this Euro model distinguish it from its North American market counterpart.

The exterior retains original paint on the metal in black with a matching aftermarket body kit.  It shows off a fresh buff / detail and has never been winter driven.  During the seller’s ownership tenure, the car has always been indoors and covered when not in use – he is including the custom fit satin cover with the sale.  The front air dam and rear bumper cover were repainted in 2019 (work order in the gallery).  The ground effects bring an aggressive look and accentuate the E24’s “shark” nickname.  The refinished 18” M-Parallel wheels reinforce the strong look, shod in Michelin Pilot Sport A/S 3+ tires with 2016 date codes and approximately 5,000 km of service.  The seller is also including the original metric-denominated wheels, there is also a spare tire on a fifth M-Parallel wheel. “M” badges on the grille and trunk lid (without “635CSi”) indicate that this is a special E24.  On the rear, the trunk lid spoiler and two chrome exhaust tips further the sport feel, as does the lip up front.  Grey side striping is tasteful and complementary.

The interior highlight is the reupholstered Recaro heated front seats, with M-striping in red, turquoise and blue.  They were recovered in Canadian cowhide.  They present very well in the photo gallery and are equipped with power controls for recline and lumbar functions.  The car is well-optioned, including a/c as well as power:  windows, door locks, antenna, steering and brakes.  The three-spoke steering wheel fronts a gauge package that includes speedometer, odometer, trip odometer, tachometer, fuel gauge, temperature gauge as well as various warning lights – there is also an “M” badge in the cluster and M-striping on the steering wheel.  Other electronics include an aftermarket JVC head unit and factory trip computer.  The owner has the original BMW AM/FM/cassette head unit and it will accompany the car to its new owner

The performance of this car is its real story.  No slouch to begin with, this car had its engine rebuilt 25,000 km ago, in 2012.  We list some of the highlights here but the authoritative source for details is the document prepared by the seller as included in the photo gallery, starting at image 62; it includes a short profile of the mechanic who carried out the build.  His name is Marcus Glarner and he is a noted BMW Motorsport mechanic, particularly for his work on BMW M1 engines, the M88.

A Car and Driver article about the M635CSi.

Hi Steve, furthermore to my previous point, the reason the posted docs are saying 635csi, it’s because in 1985 the M635CSi model was sold in Europe only, therefore when the computerized vehicle registration system was implemented in Canada no algorithm was developed to denote the M635CSi as this car model was never not sold in North America. The closest approximation as far as the provincial and mechanic shop computers are concerned is the 635csi model, but this car is the real McCoy M635CSi.

Please note that when compared to the M6 (US market car) the M635CSi is 229 lbs. lighter and a full 1 second faster in a 0–97 km/h (0–60 mph) test.

Currently, I own the E46 M3 Convertible and the E60 M5 apart from other bimmers, I’m a bit of a BMW M-car addict.

The next bit is from Wikipedia:
E24 M635CSi/M6 (1983–1989)The M6 lineage began in 1983 with the E24 6 Series (Link 2, above) range, which was powered by the M88/3 (Link 3, above) DOHC straight-six engine (which was a modified version of the engine used in the BMW M1 supercar (Link 4, above). In most countries, the model was badged the M635CSi, however the equivalent model in North America and Japan was simply badged “M6”.
The European-specification M635CSi used the M88/3 (Link 5, above) engine (without a catalytic converter), which generated 210 kW (286 PS; 282 hp) at 6,500 rpm and 340 N⋅m (251 lb⋅ft) at 4,500 rpm. The M6 version, sold in North America and Japan, used the S38B35 (Link 6, above) engine (with catalytic converter), which generated 256 hp (191 kW; 260 PS) and 330 N⋅m (243 lb⋅ft) at the same engine speeds. The catalyzed engine was also used in European and other market cars beginning in the summer of 1987, with identical specifications to the federalized engine. The sole transmission for all models was a 5-speed Getrag 280 (Link 7, above) manual transmission.
Other changes included BBS (Link 8, above) RS wheels, a rear lip spoiler, a larger front air dam, larger front brakes and revised suspension with a 10 mm (0.4 in) lower ride height.

The E24 (Link 2, above) became a world car (Link 9, above) for the 1988 and 1989 model years, sporting the same bumpers and aerodynamic treatments as its high-performance counterparts across all markets. Production of the E24 M635CSi/M6 ended in 1989.

According to BMW, the car can accelerate from 0–97 km/h (0–60 mph) in 5.8 and 6.8 seconds for the European and North American versions respectively. The curb weights of the 1987 models are 1,515 kg (3,340 lb) for the M635 CSi and 1,619 kg (3,569 lb) for the M6. A top speed of 255 km/h (158 mph) made the European M635CSi the second fastest BMW automobile ever built next to the M1 (Link 4, above). The quarter mile time for the M635 CSi has been recorded at 14.5 seconds while 161 km/h (100 mph) is achieved in 15 seconds.
A total of 5,855 cars were produced. Of these, 1,677 cars were imported to North America. Due to the elongated front and rear bumpers, the length of the U.S. models is 4,923 mm (193.8 in).

Hi Steve, this is a real Dingolfing, Germany factory made M635CSi (the Euro M6) with the factory installed M88/3 24-valve, twin cam, straight six engine, not a rebadged 635csi. Please refer to photos 43 & 44 where you can easily see the BMW factory tin plate with the car model (M635CSi) and the Vehicle Identification Number (VIN = WBAEE310601050397).

Hi Dannym, no, you don’t need a professional appraisal to license this car. The car has been licensed to drive in Canada since November 5th, 2010, the day after I crossed the US border coming back from Atlanta, where I bought the car. CCC has a copy of the Ontario issued ownership in trust. The car is insured with Haggerty as a Classic Vehicle.

I am a bit new to this…do you have to get a professional appraisal to license this car ?

Hi Mike, I am a bit confused, is it a real M6 or a 635 with “M” badging ? If it is a real M6, is there some documentation showing this, as all the docs posted say 635.

Yes, the car comes with a safety certificate. It drives like a dream.

I was unable to secure a hoist to take the underbody pics today and the forecast calls for thunderstorms Tuesday and Wednesday, so I would not be able to get these till Thursday or Friday, I won’t drive the car in rainy weather or after either, since it has been detailed with great care.

Nice looking ride…one thing about collector car Canada is that what has been listed has been quality merchandise. Sadly some have not met with the right bid.. but the back lot is a great way to buy at a great price.. way to go Dave !!

Does it come with safety certificate?
