The E24 was a replacement for the CS and CSL coupés first produced in 1965. The CS 3.0 was almost changed by adding a few inches in height to make it easier for customers to get into the car. However, Bob Lutz rebelled against the decision and rough drafted an alternative version that soon became the 6 series. Production started in March 1976 with two models: the 630CS and 633CSi. Originally the bodies were manufactured by Karmann, but production was later taken in-house to BMW.

In July 1978 a more powerful variant, the 635CSi, was introduced (for the time being not available in North America and Japan) that featured as standard a special close-ratio 5-speed gearbox and a black rear spoiler.

In 1979 the carburetted 630CS was replaced with the 628CSi, this car had a fuel injected 2.8L engine taken from the BMW 528i.

In 1982 (Europe) and 1983 (US), the E24 changed slightly, with an improved interior and slightly modified exterior. At the same time, the 635CSi received a new engine, a slightly smaller-bored and longer-stroked 3430 cc six to replace the former 3453 cc engine and became available with a wide-ratio 5-speed or an automatic.

E24's produced after June 1987 came with ellipsoid headlamps instead of the halogen lamps of earlier models. The sleeker European bumpers were also discontinued. Previous cars had either a European-standard bumper or a larger, reinforced bumper to meet the US standard requiring bumpers to withstand impact at 5 mph (8 km/h) without damage to safety-related components. 1989 was the last year for the E24 with production stopping in April. The E24 was supplanted by the considerably heavier, more complex, and more exclusive E31.

I am offering a beautiful 52,000 miles, two owner example with full service history and a complete tray of original tools to the boot compartment. The 628 CSi is exceptional to drive being smooth and powerful. A great car to drive even in today's road conditions. It comes with electric sliding steel sun roof, electric windows, electrically operated door mirrors, power steering and the original BMW stereo with security card still present and working. This is not an average example. Currently MOT tested until January 2011. Delivery arranged.
