The Car Connection's Take
TCC Rating
8.4
9.2
TCC’s Bottom Line
A powerful near-exotic luxury convertible, or a grand tourer with German precision? The 2012 Mercedes-Benz SL Class is both. A marriage of the best of German handling and Italian power, the 2012 Audi R8 is a fantastic all-around supercar.
