The Car Connection's Take
TCC Rating
8.2
9.0
TCC’s Bottom Line
The 2015 Mercedes-Benz SLK-Class combines mini-SL style with a choice of efficient or potent powertrains, but it's better suited to cruising than corner-carving. The 2015 Porsche Cayman remains a focused 911 alternative, at an easier-to-swallow price.
