1985 BMW M635 CSi (E24)

Elevating its stylish, elegant 6-Series from a luxurious GT to an outright supercar capable of mixing it with contemporary Porsches and Ferraris, BMW launched the M635CSi at the 1983 Frankfurt Motor Show. Designed by BMW's Motorsport division, the M6 was powered by essentially the same 24-valve M88 straight-six as featured in the mid-engined M1, except for having wet sump lubrication, a higher 10.5:1 compression ratio and Bosch's latest ML-Jetronic fuel injection. With a close-ratio, Getrag five-speed gearbox, the only transmission available, the M6 also boasted Bilstein dampers, higher spring rates and a lower ride height to sharpen up the handling, plus a ZF limited-slip diff to handle the 286bhp on tap.

Make no mistake, this big BMW was a seriously quick motor car, with 0-60 mph dispatched in six seconds flat on the way to a top speed of more than 150 mph. Keeping all this performance in check were cross-vented disc brakes with ATE four-pot callipers and ABS was standard. Unlike most supercars, the M6 added the practicality of a cabin capable of seating four adults in comfort, plenty of luggage space in the boot, and relatively moderate running costs (for a Supercar!). The Recaro front seats and Motorsport steering wheel also set the model apart from lesser 6-Series and its M-Sport identity added muscle to the BMW's lithe styling, with discreet 'M' badges and wider alloy rims filling out the flared arches. A driver's car par excellence, the ultimate 6-Series derivative has always been sought after and thanks to its rarity (just 5,859 were built), its status as a classic is assured.

Supplied new in September 1985 by H E Averill & Sons (BMW) Norwich to Mr R Fawn, this Alpine White M635 CSi is in outstanding time warp condition throughout and has never been welded or repaired. With a current recorded mileage of 53,355 and a comprehensive and known history from day one, this appreciating modern classic with just four former keepers has clearly led a cherished life supported by the comprehensive service records and MOT certificates that detail its motoring adventures to date (further information is available upon request). A fresh MOT inspection has just been undertaken with new certificate issued without advisories. Recent expenditure includes a complete wheel refurbishment and bearing in mind the originality of this particular M635, a brand new set of correct Michelin TRX tyres have been fitted, it should also be noted that the original radio accompanies the vehicle. With just 522 right-hand drive examples of the M635 CSi produced, and few remaining in this condition, this rare and desirable BMW will be welcome within any collection or showing its heels out on the open road. Your early inspection is welcomed and encouraged to truly appreciate this exceptional ‘Shark Nose’.
