TCC’s Bottom Line

The 2018 Mazda MX-5 Miata is the quintessential modern sports car.

The 2017 Mercedes-Benz SLC-Class dukes it out on comfort with more sporting rivals.

TCC Likes

Light and lean
A visual knockout
Stays true to its pure driving ethos like few other cars

Top-up refinement
The more affordable SL
Great features—like Airscarf

TCC Dislikes

Little room for small and large item storage
Price can climb fast
Challenging infotainment system

Not sharp enough for some driving enthusiasts
Tight for tall drivers
V-8 is gone
