TCC’s Bottom Line

The 2017 BMW M3 is a track-ready sports sedan with an unblemished pedigree that announces to the world: "Ask me what DTM means." The 2017 Mercedes-Benz C-Class adds to the impressive roster with a convertible version this year and a newly minted AMG C43 version. Bavaria is even better now. The 2017 Porsche 718 Boxster and Cayman remains some of our favorite performance cars; they're thrilling to drive, and in base form they're exceptional sports car value, too.
