2008 BMW 3 Series Sedan 328i 4dr Sedan (3.0L 6cyl 6M)
Why BMW?
 I hesitated before purchasing the 328i.  In fact, I opted for a 2007 MB C230 Sport for my wife after test driving the then-new 335i in 2006.  Realistically, I do not see how a daily commute needs 300+ hp.  The 328i provides adequate handling even w/o the sport(y) package when compared to the RX8 I traded in.  Unfortunately, the 16" runflat all-seasons are a poor compromise.  Highway expansion joints are much more noticeable than the MB.  The MB has 17" performance tires w/ lower profile.  BMW also worked diligently on cost-cutting when packaging the E90.  Where is the standard alarm? Where is the jack? How about a real cup holder? Still, the 328i puts a smile on my face every morning.
