2018 Bentley Bentayga Onyx Edition 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.

2018 Bentley Bentayga
KBB.com Review
When money is no object, the object of your automotive desire should be the 2018 Bentley Bentayga luxury-crossover SUV. Unlike some rivals, this SUV can actually tackle the toughest off-road obstacles and with a top-speed of nearly 190 mph, the Bentayga is also the world’s fastest production SUV.
Styling is subjective, but we think there are a number of more distinctive luxury SUVs offering the same or better off-road performance for a lot less money. Land Rover offers a number of options, as do Porsche, Mercedes-Benz and Audi.
