I'll take the M3 Compact, as it's likely worth a fortune.
In 1996, to celebrate the 50th birthday of the German automobile magazine Auto, Motor und Sport handbuilt (at least) one M3 compact. The car embodied all the technical and optical characteristics of the stock E36 M3, but in the compact body, and more. A quad exhaust tip, Recaro sports seats, four-point seatbelts and an alcantara steering wheel and gear lever were specific for this model. The car was widely regarded as a test mule for the Z3 M Coupe. The car was donated to the automobile magazine, and currently resides in the M GmbH headquarters in Garching, Munich.
Probably is.
There's alot of modified ones that are about though,
