Reviewed a 2020 Cadillac CT4 on Mar 13, 2022
The Cadillac CT4 Premiere Luxury is well appointed for the price point of the vehicle. The interior is more luxurious than other luxury vehicles I considered in my search. The Acura TLX A-spec is a beautiful car on the outside, however does not look like a luxury car on the inside. For a 4 cylinder with turbo, the car responds like a V6 with plenty of get up and go. I would definitely recommend this vehicle.

Looks great. Rides great. But no safety rating. Car came out in 2019. Still no safety rating. Why?
