This E24 was modified by legendary BMW tuners Miller and Noburn out of North Carolina, who also happened to prepare many BMWs for IMSA and SCCA races. They were one of the only certified Alpina dealers in the US in 1979 and they modified this car to Alpina spec when it was new.
A high-performance cam, Super Sprint headers, an Italian PrimaFlow exhaust, and lightened flywheel were installed, and an Alpina FC6 chassis system was added utilizing lowering springs, 21 mm front shocks, 18 mm adjustable rear shocks, sway bars, and front and rear hard rubber chassis mounts. Color-matched 16” Alpina forged alloy wheels were also fitted.
It appears that there’s a small dent in the driver side fender, but the rest of the factory paint exterior, as well as the totally original tan leather interior, seem to be in great shape. The seller mentions recent maintenance and notes that he is the second owner since 1993.
The asking price here is right around E24 M6 values, so it’s tough to spend that much on a 633 CSi, but we feel that since Miller and Norburn added all the Alpina goodies that this car is worth it. Oh, and did we mention the cool Topaz Brown exterior color, the wooden Alpina steering wheel, and the vintage cell phone? Yeah, we are all in on this one.
