We bought ours used w/39k miles on it. The car is beautiful, well maintained. I have one problem with an ESP/BAS warning and this appears to be affecting the operation of the sunroof. Hopefully this can be corrected by the certified warranty. The car feels as solid and safe as any car I've driven and after I got finished with it this weekend you can't tell its not new.
The overall look, classy interior. For those of you complaining about the back seat, it has a bigger back seat than my Crossfire!
Cupholder awful, same issue w/ Crossfire of which Mercedes is a builder. I hope the BAS/ESP is not going to be a problem. My Crossfire's light comes on from time to time and it can easily be reset. There should be a reset on the Benz if there isn't a real problem. Its a complicated car to learn.
