Find another car under $20-30k with such a great chassis, competent handling and smooth engine. Plus it is still one of the best looking coupe's on the road and has enough stock HP to keep most driver's entertained when needed.
Lovely car. One of the best cars BMW have made, in my opinion. If I didn't need 4 doors, I would have replaced mine in a heartbeat. And I would have had no issue with paying 25-35k for a super low milage example that is well maintained (6spd, coupe obv).
