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.
