2010 Audi A4 2.0T Premium 4dr Sedan (2.0L 4cyl Turbo CVT)
Lease was ending on a 2007 A4, and looked at the BMW 328, Mercedes 350C, and G37 as well as the 2010 A4; This car had the best balance of performance / luxury relative to price of anything I looked at (I have the Premium Plus and Sport Package). Don't be put off by the 4 cyl turbo - driven in "S" mode the car has as much, if not more, acceleration as the others and is a blast to drive. I'm looking forward to three great years with this one!
iPhone integration (and MMI in general) snazzy 18" sport wheels, interior design. Overall driving experience.
Bring back the 12 volt adapter in the trunk. Also, the second cup holder is basically unusable for shorter drivers.
