Should I buy a used Cadillac CT4 now or wait for the next model?

Buy now if:

• Price trend: The 2025 model is at −6.78% versus a year ago, and the 2024 model is at −1.44%.
• Deal availability: The 2025 model has 33.7% good and great deals, and the 2024 model has 34.8%.
• Sweet-spot year: The 2024 model has the most listings at a current average price of $32,297. The Cadillac CT4 offers a distinctive rear-drive sport-sedan character that stands out for shoppers who want something different from the usual compact luxury formula.

Consider waiting if:

• Powertrain/efficiency: Cadillac employs a turbocharged 2.0-liter four-cylinder engine as the standard power plant for the new CT4. It whips up 237 horsepower at 5,000 rpm and 258 pound-feet of torque between 1,500 rpm and 4,000 rpm, which is plenty to motivate the test car’s 3,455-pound curb weight. Donated by GM’s full-size pickup trucks, a turbocharged 2.7-liter four-cylinder is also available, supplying up to 325 hp and 380 lb-ft of torque.
• Tech: It has an 8.0-inch touchscreen display with high-resolution graphics, a simple menu structure, and quick response to inputs. Standard Apple CarPlay and Android Auto allow you to run smartphone apps, while Near Field Communication Bluetooth pairing simplifies your life.
• Safety: If you want forward-collision warning or low-speed automatic emergency braking with pedestrian detection, you must upgrade to Premium Luxury, Sport, or V-Series trim. Then, once you’ve upgraded, you must select the Driver Awareness Plus Package and the Driver Assist Package to get the full set of ADAS.
• Starting price: Prices start at a remarkably low $32,995.

If you're buying used today, the 2024 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for the next model year's inventory to build up.
