The most coveted model at the time and today by collectors of the BMW 6 Series E24 range is certainly the M635CSi (1984-1989), which also served as the basis for the homologation for the Group A versions used in the touring championships. But the entire 6 Series E24, presented in 1976, deserves attention. All 6-cylinder engines (carburetor or injection) are particularly bright and fun. To fully enjoy the comfort of this 4-seater coupe, the 628CSi (184 horsepower), 630CS (185 horsepower) or 633CSi (200 horsepower) versions are more than enough. As a sports model, the 635CSi was presented in 1978, with a 218 horsepower engine and optional special gearbox.
