The Car Connection's Take
TCC Rating
8.4
8.6
TCC’s Bottom Line
The 2009 Infiniti G37 Coupe does a neat convertible trick: it keeps all the charm of the Coupe while opening up more to the world outside. The 2008 BMW 3-Series sedan has the best overall driving experience in its class and remains the gold standard among mid-size sport sedans.
