Just picked up a 2003 M3 Cabrio SMG to go along side my Z4 M. My "new" M3 only had 5900 miles at delivery to me. Car is essentially new, except for a small spot on the driver's seat bolster where the previous owner rubbed off the dye getting in and out. There's also a very small scratch on the hood from a stone. But no dings and the wheels haven't come close to a kerb. The car is bone stock and will remain that way for now. Any advise on how to repair (re-dye) the spot on the seat bolster? Anyone make a DIY repair kit? Today the car got a thorough wash, and later today it'll get clayed, polished, and waxed!
