I had a clean 85 635csi 5spd for several years. Honestly it was a great driving car, but a real money pit. Fastest rusting car I've ever seen. After 3 years of ownership the climate controls were still a mystery to me. The sound of that straight six @ 6000 rpm was pure goosebumps though and it pulled like a freight train. They look fantastic as well. I'd love to own an M6 someday.
