The Car Connection's Take
TCC Rating
6.7
6.6
TCC’s Bottom Line
The 2020 Audi A3 is a well-equipped entry-level compact sedan that delivers more substance than flash. The 2020 Mercedes-Benz A-Class sedan is the most affordable new Mercedes on sale. Its three-pointed star will be the attraction, but there’s plenty to stick around for after.
