TCC’s Bottom Line

The 2020 BMW 3-Series is back on top among compact sport sedans, even as the competition closes in.

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

TCC Likes

Dual personality
Longer, wider, stronger
Impressive technology

Have it your way body styles
All of which are gorgeous
Strong powertrain lineup

TCC Dislikes

8-speed automatic only
Added dimensions don’t add much inside
No electrified powertrains to start

Manual would be nice
Hefty pricetag
Rear-seat and cargo space just so-so
