So it has been six weeks since taking delivery of my CPO 2012 Signature P85 (21K Miles). Having read all of the horror stories posted on TMC about various issues including dead 12v batteries, drivetrain issues, etc....I was expecting the worst given that my car is VIN# 233...one of the first ones off of the line. At the same time, I was hoping that all of the car's issues had been addressed during the previous two year ownership. Since Tesla does not disclose the previous service history, it is impossible to tell what issues occurred and were addressed. Happily, except for a slight bit of wind noise on the driver's side window, the MS has been absolutely trouble free in all respects. Everything works, everything fits and the car is a joy to drive. It has exceeded my expectations. The only thing that I would change would be to install 19" wheels instead of the 21"s, but I am learning to live with them. I am getting ready to buy snow tires for the upcoming winter season, and there are not a lot of tires to choose from. Any recommendations would be welcome. Tesla is also opening a major new Store/Service Center in Dedham, Mass, 30 miles from me this summer! Knock on wood!
