2005 BMW 6 Series Convertible 645Ci 2dr Convertible (4.4L 8cyl 6M)
Wonderful car but too many problems!
 We loved everything about our 2005 645I convertible.  Talk about a car that catchs everyone's eye and is a blast to drive!  But....we had so many problems with ours we regretfully ended up giving it back under the lemon law.  It was in the BMW service dept 32 days between July 6 and Oct 1, 2006 - not counting weekends!  We were told it had 19 computers by 15 manufacturers and the glitchs weren't worked out yet.    We expected more from an $80,000 car but agree we'd buy another one if we were promised it wouldn't have so many problems!
