TCC’s Bottom Line
The 2021 Audi A4 blends a conservative luxury compact car with spicy performance and robust wagon flavors. The flexible 2021 BMW 3-Series lineup offers something for everyone, so long as they’re not smitten with SUVs. Svelte, sporty, and somewhat understated, the 2021 Mercedes-Benz C-Class should be at the top of your compact luxury sedan shopping list.
