The Car Connection's Take
TCC Rating
7.8
6.8
TCC’s Bottom Line
The 2017 Mercedes-Benz SL-Class isn't quite a sports car, but it's a rapid, open-air touring coupe extraordinaire. The 2017 BMW 6-Series is a luxurious jack of all trades (speed, style, comfort, and quality) but a master of one: grand touring.
