The beautiful E24 6 Series was blessed with a long sharknose bonnet and short rear deck to give it almost perfect proportions — but in 1982, Alpina threw the kitchen sink at the 635CSi to create an ultra exclusive batch (limited to just 30 units) of the B7 S Turbo Coupe. Famed for its spoked wheels and turbocharged motors, Alpina brought the best out of the BMW with each of the 6 Series cars getting a special dark green metallic paint job, gold Alpina stripes (some even got a tartan interior that would make Golf GTI fans smile...) along with a massive performance upgrade to become one of the most desirable cars of the decade.

This wasn’t just another spruced up Bimmer; hand-built in Buchloe, Germany, the Alpina-engineered enhancements included a modified cylinder head, lightweight pistons, performance camshaft, and a high-flow exhaust header with three-inch exhaust piping. It also got an upgraded chassis (new shocks, springs, and additional bracing) and though it weighed 1,500kg, the B7 S 3.5-litre blown inline-six produced 330 horsepower and 500Nm of torque — an insane amount for the time. That power was sent through a five-speed manual gearbox to the rear-wheels and it could despatch the 0-100kph sprint in just 5.7 seconds. With a top speed of 269kph, it was one of the fastest cars of the period.

They hardly ever come up for sale but one recently did — and it was listed for $300,000 (Dh1.1 million) which is a lot even for such an extremely rare piece of Teutonic perfection. But, just look at it... Don’t you just wish you were seriously flush with cash?
