The list is too long but the M5 is mechanically new. The past owner spent over $9,000 on the parts for just the engine. Studded heads and mains. 11 to 1 pistons and every part internally new. Rebuilt transmission, drive shaft, rear, brakes, suspension. But the paint sucks and the leather is in great need of replacement. What is it's value? How does the group see the E28 M5 appreciating? I am $7,000 away from perfection. Will it be worth $20,000? Now? Soon?
