TCC’s Bottom Line
The 2021 Acura ILX is cheap for a luxury badge, but it’s not especially luxurious. The 2020 Audi A3 is a well-equipped entry-level compact sedan that delivers more substance than flash. The 2021 Mercedes-Benz CLA-Class is a stylish little sedan with plenty of personality and a hefty price tag.
