'08 MM purchased used 11/10 with 29k, now has around 31k. Daily driver. No problems, other than some mild shock at the $2k brake job.
Previous owner mentioned that he had an issue with the suspension that had been making it a bit squirrely around 130mph, and the dealer had replaced some sort of arms or brackets under warranty. I haven't yet had it up to speed to test that
When I had the car before being sold in July 2010 I accumulated 32,500 on the dot..
No problems what's so ever.The Car was bought brand new in March 08 when it first came out..
Drove it out hard and race it practically every chance I had!
