2010 Infiniti G37 Sedan

Base MSRP $33,250

The new engine in the G37 made it onto Ward's Ten Best Engines list for its performance, while the interior comfort and amenities give the car a luxury feel. According to Infiniti, the new interior was inspired by Japanese calligraphy, and new fascias on the sedan help to increase the G37's curb appeal. The addition of the convertible model last summer completes the sports-luxury lineup -- putting it solidly in competition with the BMW 3 series.
