"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 six seconds on its way to a top speed in excess of 155mph.
This fabulous matching numbers M88 powered 'Shark' comes from a private BMW collection and is presented in probably the best colour combination of Cosmos Blue with classic blue houndstooth interior. The present owner is only the second recorded owner after GB UK. The car is accompanied by an extensive history file including the original owner’s handbook and service book in its original wallet. There are also many invoices, old MoT test certificates and a present MoT test certificate which expires in June 2020. After purchasing the BMW in 2016, the vendor had some of the car refurbished to bring it up to the fantastic standard that it is today (photographs of this work can be found within the history file) and, in 2018 the car received a mechanical and electrical refresh by BMW marque specialists Retro Engineering of Redditch. All the electrics are currently in working order including the air conditioning, sunroof, front and rear windows, seats and headrests. The car drives extremely well and still feels quick on the open road even by today’s standards."
