Hi. I'm in the process of purchasing a 2006 M6 and I was hoping some of you could give me some ideas on what to inspect from a mechanical reliability point of view. I'm putting together a checklist. I'm already aware of the SMG clutch problems, the oil cooling unit leak issues and the convertible RED light issue (although I don't think I'll be getting the coupe). The cars I'm looking at have between 38K and 55K miles on them. Any pointers on what to look for and what to get on the car would be greatly appreciated.
