TCC’s Bottom Line

Affordable fun remains the 2020 Mazda MX-5 Miata’s calling card, and we can’t get enough of it.

The 2020 Mercedes-Benz SLC-Class sings a pretty swan song—and you can hear it even when the top’s down.

TCC Likes

Fun to drive at every speed
181-hp engine has verve
Notchy, addictive 6-speed manual

SLC 43 is a true sports car
Foldable hard-top refinement
More affordable SL-Class

TCC Dislikes

Frustrating infotainment system
Prices have crept up
Limited room for big passengers

Not being replaced after 2020
Tight for tall or wide drivers
SLC 300 is not as fun as it should be
