Imperial War Museum | Duxford, Cambridgeshire 35000 - 45000 Registration No: F475 JUE Chassis No: WBAEE320400760452 MOT: September 2025 � A well-maintained rare M635 CSi Highline 'sharknose' � Sytner BMW-supplied in Diamond Black Metallic with Silver Nappa leather � A full repsray in 2020 with an engine overhaul and recommisioning � Displayed mileage of c.131,833 with major mechanical works carried out � 5 former keeper/company changes (3 the same person) and stored for many years prior to work Elevating its stylish and elegant 6-Series from a luxurious GT to an outright supercar capable of mixing it with contemporary Porsche and Ferrari models, BMW launched the M635 CSi 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 5-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 0-60mph despatched in six seconds on the way to a top speed of more than 150mph. Keeping all this performance in check were cross-vented disc brakes with ATE 4-pot callipers and ABS as 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.
