TCC’s Bottom Line

The 2018 BMW 4-Series is an above-average coupe or convertible with sharp road manners and confident powertrains. The bad news? The 4-Series has personality like business casual.

Very expensive and still not very large, the 2018 Mercedes-Benz C-Class nonetheless leads its luxury niche with fabulous style and fantastic power and grip.

TCC Likes

Handsome shape
Compelling base engine
Responsive automatic transmission

Coupe, convertible, or sedan

TCC Dislikes

Staid exterior style
Baffling tech packages (and prices)
