2008 BMW 3 Series Convertible 328i 2dr Convertible (3.0L 6cyl 6M)
Great Vehicle
 Upgraded from a 2003 Z4 to the 2008 328 Cabriolet.  No regrets whatsoever.  Wanted a bit more room than the Z4; and the hardtop convertible for more security, less maintenance, and better sound and cold insulation.  For about $6k difference in price, couldn't see the justification for the 335; the 328 has plenty of power.
