The Car Connection's Take
TCC Rating
8.2
8.8
TCC’s Bottom Line
The 2016 Mercedes-Benz SLK-Class is more of a weekend-getaway machine than a canyon-carver; but with mini-SL style and some unrivaled tech features, if offers up roadster thrills with fewer sacrifices in comfort. The 2016 Porsche Boxster is a thrill to drive; but beyond that it's a great car in nearly every way, and one of the best-value sports cars you can get.
