BMW E30 M3 S50B30

BMW E30 with S50B30 M3 engine. The car is capable of sub-2 minutestimes on Zandvoort (old layout), and 2:50 at Spa Francorchamps. If you think of a BMW E30 as a nice race car, then this is a *very* nice car which is quick, predictable and neutral in corners. At trackdays (including English ones), the car is usually one of the quickest, outpacing theoretically much more potent machinery.

The car has not been raced and has not been damaged. 

Important – this is not a modified rusty streetcar, but rather a new car that was carefully and purposefully engineered for track use.

Priced at € 17,500 (including trailer and wheels).

No trailer? Then it is € 16,500.
