I have owned my convertible for a yr and love it. No issues with it so far, 12500 miles.
I have the M-sport pkg, 19" 230 wheels, NAV, oyster & black interior, and installing the PPK and PE this week. Planning on keeping her 6yrs/100k miles or longer if I have no issues. If you want a convertible the 335i is perfect.
