The Car Connection's Take
TCC Rating
7.5
7.0
TCC’s Bottom Line
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 2018 Infiniti Q50 is powerful, well-equipped luxury sedan that doesn't quite match up to Germany's finest yet.
