While the 50i (2011) has some serious appeal (as does the X5M), I cannot find enough positive adjectives to describe my experience and satisfaction with the '09 35d.

I would drive the 35d for the rest of my existance and be thoroughly satisfied. I never thought I'd say that (Ok, perhaps a 911 would be a nice addition), but after 16 months (and 7k miles) of the 35d, I'm happy as a lark.

Power, sound, fuel efficiency, reliability, build quality, 6-speed auto (w/sport package), everything is perfect.

Hope this opinion helps.
