The Cadillac CT6 was the brand's flagship sedan from 2016 to 2020, developed to compete with top-tier German rivals. It was built on the advanced, aluminum-intensive Omega platform, giving it a weight advantage and sharp handling for its size. The car offered a range of powertrains, including a plug-in hybrid, but North American production ended after just 5 model years.
Collector focus is almost entirely on the limited-production CT6-V. Initially called the V-Sport for 2019, this model featured the exclusive 4.2-liter twin-turbo "Blackwing" V8. This hand-built, 550-hp engine was used only in the CT6, making these cars instant modern collectibles. Standard models are also gaining notice for their technology, including the Super Cruise semi-autonomous system, and for offering significant luxury at a depreciated price point.
With only 21 transactions tracked, the CT6 market is thin and highly dependent on specification. The average price of $33,245 is skewed by the wide gap between common V6 models and the rare, valuable CT6-V. Top-tier V models are holding their value well, while standard versions represent a significant used luxury bargain.
Buying Tips
- The main collectible is the CT6-V with its 4.2L twin-turbo "Blackwing" V8. Demand detailed service records for this complex, low-production engine.
- Test the Super Cruise hands-free driving system on an approved highway to ensure it functions correctly, as repairs can be complex.
- Check the responsiveness of the CUE infotainment system, which could be laggy on earlier 2016-2017 models.
- The aluminum-intensive body construction is expensive to fix. Carefully inspect all panels for signs of poor accident repair.
- The 3.0L twin-turbo V6 is a strong performer, but be aware of potential maintenance costs. The 10-speed automatic found in 2019-2020 models is a desirable upgrade.
Prices range from under $100 for project cars to $81,000 for top-spec CT6-V models.
