The Car Connection's Take
TCC Rating
8.4
9.0
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. The 2012 Porsche 911 is one of the best buys in the sports car market, and quite possibly the most practical, luxurious car at its performance level available.
