The Cadillac CT6 was GM's flagship luxury sedan from 2016 to 2020, built on the advanced, aluminum-intensive Omega platform. It was designed to compete with German rivals, offering a tech-forward cabin that included the impressive Super Cruise hands-free driving system on later Platinum models. Despite its technical achievements, the CT6 was discontinued in North America after a short production run, making it a relatively rare sight.
Most of the collector interest is focused on the 2019-2020 CT6-V. This limited-production model features the exclusive 4.2-liter twin-turbocharged 'Blackwing' V8, producing 550 horsepower. These are genuine future classics with a dedicated following. Standard models, powered by 4-cylinder or V6 engines, aren't traditional collectibles but have depreciated into compelling bargains for those seeking modern luxury and technology for a fraction of the original cost.
Based on 16 sales, the market for non-V models is soft, with an average price of just $17,296. The low end of the market includes project or parts cars, while the high end around $37,000 represents clean, low-mileage examples of the 3.0L Twin-Turbo or Platinum trims. The exclusive CT6-V trades for significantly more and isn't reflected in these average sales figures.
Buying Tips
- Test the CUE infotainment system thoroughly for slow response times, freezing, or screen delamination. Ensure it has the latest available software updates.
- The 3.0L twin-turbo V6 is powerful but complex; check for a complete service history and look for any signs of oil or coolant leaks.
- If equipped with Super Cruise, verify its functionality on a compatible highway. The system requires a subscription and all sensors to be in perfect working order.
- The aluminum and steel body panels are expensive to repair. Inspect carefully for signs of previous accident damage and ensure any repairs were done by a certified shop.
- Check all electronic features, including the digital rearview mirror, 360-degree cameras, and power seats, as repairs can be costly.
Observed sales range from as low as $99 for project cars to $37,000 for well-maintained, late-model examples.
