2020 Cadillac CT6 3.6 Premium Luxury Sedan 4D Depreciation
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.

2020 Cadillac CT6 3.6 Premium Luxury Sedan 4D Standard Features
2020 Cadillac CT6
KBB.com Review
You want luxury goods without the “goodness me” pricing. The 2020 CT6 represents even better value than last year’s model (see the What’s New section) with previously optional features becoming standard. And maybe you also want to fly the American flag while you’re saving thousands of dollars.
You realize that the price of entry is one thing, the price of exit is another. At some point down the road, you’re going to want to sell your CT6, which is when resale values come into play. The perennial winner of this game is Lexus and a comparable LS flagship sedan will be worth more.
