Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.

2018 Cadillac CT6 3.6 Premium Luxury Sedan 4D Standard Features
2018 Cadillac CT6
KBB.com Review
Kbb.com Expert Rating
The Cadillac CT6 is the best interpretation yet of Caddy’s Art and Science design language, and its uniquely American interior sacrifices no luxury to its European and Japanese competitors. The high-tech features will capture the attention of younger buyers, and its turbocharged engines and excellent handling will win over enthusiasts.
There’s no long-wheelbase version, and while the back seat is available with an executive package, the CT6 is shorter than many rivals. There’s also no V8 available, and while the CT6 is a very nice luxury sedan, Cadillac still needs to rebuild its brand equity to BMW and Mercedes-Benz levels.
