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 redesigned 2021 BMW 4-Series has evolved into a technology powerhouse with wonderfully responsive powertrains, but the coupe lacks playfulness. Svelte, sporty, and somewhat understated, the 2021 Mercedes-Benz C-Class should be at the top of your compact luxury sedan shopping list.
