What should I look for when buying a used 2020 Cadillac CT6?

At 60.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm that the car’s accident record matches the seller’s disclosure. Then put inspection priority on body condition, panel alignment, and signs of prior repair work, since those are the areas most likely to reveal whether a past incident was minor or more serious. It also makes sense to focus on overall wear and maintenance consistency so you can separate a clean, well-kept example from one that only looks good on the surface.
