The E24 6 series was produced from 1976-1989 and was the replacement for the CS and CSL E9 coupes. Like the E9 coupes, the early bodies of the 6 were manufactured by Karmann until production was moved in-house by BMW. It was the proven E12 5 series that provided the chassis and much of the mechanicals for the E24. Dubbed the ‘Bavarian Ferrari’ the 6 series was a high end two door luxury sports coupe. The 628 model was produced until 1987 and was a budget model for the European market. The 633 Csi featured the first generation of DME and ABS brakes were available as an option. The following year, the 635 CSi received the same DME as the 633 Csi.
E24s produced after June 1987 were fitted with ellipsoid headlamps, as per the recently introduced E32 7 Series. The front and rear bumpers and spoilers were redesigned to use a single design worldwide, and the engine was updated to the higher compression M30B35 type.
This wonderful late Highline model was in the ownership of just one keeper for nearly 20 years, during which it was maintained only by Central London-based main agents. The 635 was used only in the summer, and when not in use stored carefully in an underground garage and valeted regularly. As a result the 635 is in beautiful rust-free condition, unlike many others on the market. Showing just 53,000 miles from new, three owners and with full service history, this is a truly collectors grade example of BMWs flagship GT car.
