I have a 2010 model II that I purchased in the summer of 2009 --so it's an early build. I've had a few gremlins -- e.g. an SKS system that seems to vary in whether it unlocks all doors upon the driver's door being unlocked. But I had had *no* maintenance other than the usual routine stuff. (The car has over 65,000 miles on it.) I did replace the tires, but of course that's to be expected. Do not be afraid to buy a 2010.
