Why not go for an older M3 4-door and have it worked over by Dinan? Probably end up costing the same money as a later M3, if not less, and should be really quick and refined.

For example, Carmax has a '98 M3 sedan (auto) for $20K. Dinan's Stage 3 setup adds a supercharger and full suspension plus other stuff for $10K more. Bumps it to 340 horsepower and 307 lb/ft torque.
