overall
Summary
With 171 currently listed for sale and an average price of $24,545.00, 29.8% of 2020 Cadillac CT4s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 Cadillac CT4 4 / 5 stars.

The 2020 Cadillac CT4 features a turbocharged 2.0-liter engine producing 237 horsepower and comes with a range of trims to suit different driving preferences, including the sporty V-Series.
Why it stands out
The 2020 Cadillac CT4 stands out in the competitive luxury sedan segment for its sporty driving dynamics and striking design, which is reminiscent of the more athletic Chevrolet Camaro. The CT4 offers multiple powertrain options and a modern infotainment system featuring an 8.0-inch touchscreen and smartphone integration, enhancing the overall driving experience. While the vehicle delivers impressive technology and a well-equipped interior, it is also criticized for a lack of standard advanced safety features and a performance that feels fairly pedestrian compared to its European rivals. Nonetheless, its rear-wheel drive and excellent handling make it appealing to driving enthusiasts who appreciate a sportier ride.

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?
