The Car Connection's Take
TCC Rating
7.8
8.2
TCC’s Bottom Line
The 2013 BMW Z4 is spirited and purposeful, and balances fun and comfort quite well, but it's pricier than other roadsters. The 2013 Infiniti G37 Coupe is a sexy, lavishly equipped luxury car that isn't quite up with its German targets for refinement, but enthusiasts may prefer its sharper performance.
