The Car Connection's Take
TCC Rating
8.6
9.0
TCC’s Bottom Line
The 2012 Mercedes-Benz SLS AMG has those stunning gullwing doors, but but we'd take the Roadster any day--all the better to savor the sounds from that epic AMG V-8. 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.
