"The BMW M635CSi was the brainchild of BMW’s Motorsport department and arrived to the market in 1984. Karmann manufactured the early 6-Series BMWs from launch in 1976 before BMW took production in-house. The engine was a development of the M1 supercar's 3453cc, 24-valve, six-cylinder unit producing 286bhp, the increased power necessitating chassis improvements which included altered weight distribution, revised suspension, larger brakes and a limited-slip differential. There was also a close-ratio five-speed gearbox (or four-speed multi-mode auto) and a more luxurious interior, while outwardly this ultimate 6-Series model was readily distinguishable by virtue of its 'M Technic' body kit. Performance was impressive with the M635CSi being capable of reaching 0-62mph in around 6 seconds on its way to a top speed in excess of 155mph.
Originally registered on 14th November 1986, this M635CSi has only had two former keepers and has covered 84,581 miles from new, averaging less than 2,800 miles per annum. The current vendor has looked after this BMW exceedingly well; she comes with the original service booklet with 22 stamps, together with a good history folder. Finished in Acacia Green with matching interior, this BMW has been garaged correctly and as such, presents in very good order throughout. During our inspection the engine started immediately when requested and sounded superb with no adverse noises or rattles; we are advised by the vendor that she drives with no known faults. Fitted with a generous factory specification, this car has the optional deep dish alloy wheels to complement its handsome lines. Supplied with a V5C registration document and a current MoT test certificate valid until 17th May 2018, these superb machines are rapidly becoming sought after by enthusiasts and collectors alike.
