The Car Connection's Take
TCC Rating
6.2
7.2
TCC’s Bottom Line
The 2018 Mercedes-Benz CLA-Class is a gorgeous shape in an impressive package. Equally impressive? Its ability to get expensive, even despite being the most affordable sedan in Mercedes' stable. The 2018 Audi S3 is a blast to drive, but it suffers from a tiny rear seat and the Volkswagen Golf R offers the same performance with more room for less.
