The Car Connection's Take
TCC Rating

7.3
TCC’s Bottom Line
The 2020 BMW 3-Series is back on top among compact sport sedans, even as the competition closes in. The entry-level 2020 Cadillac CT4 sedan presents a value that is quickly eroded by a lack of features standard on other luxury makes. The 2020 Mercedes-Benz C-Class is as gorgeous inside as it is outside, and it has moves to match.
