The Car Connection's Take
TCC Rating
7.0
6.2
TCC’s Bottom Line
Spin the bottle, hit the 2021 Audi A5 convertible, coupe, or hatchback, and you’re a winner. They’re all good-looking. The entry-level 2020 Cadillac CT4 sedan presents a value that is quickly eroded by a lack of features standard on other luxury makes.
