The Car Connection's Take
TCC Rating
7.8
8.2
TCC’s Bottom Line
The 2011 BMW Z4 is an exhilarating sports car, and one of the better choices for touring, but next to other roadsters it's pricey. The Infiniti G37 Coupe and G37 Convertible wow with sexy exteriors and lavish interiors, along with excellent performance, but they don't always meet expectations for refinement.
