TCC’s Bottom Line

Spin the bottle, hit the 2021 Audi A5 convertible, coupe, or hatchback, and you’re a winner. They’re all good-looking.

The luxury coupe gets longer, stronger, and loaded with more features.

The 2020 Mercedes-Benz C-Class is as gorgeous inside as it is outside, and it has moves to match.

TCC Dislikes

Cramped coupe and convertible
Gets pricey in a hurry
Some colors are a downer

Big dumb butterfly grille

No manual, no cry?

Hefty pricetag
Rear-seat and cargo space just so-so
