The Car Connection's Take
TCC Rating
7.8
8.4
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 2010 Mercedes-Benz SLK-Class has the poise and performance of a sports car and the soul of a sunny roadster.
