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 Mercedes-Benz G-Class G 550 Sport Utility 4D Standard Features
2018 Mercedes-Benz G-Class
KBB.com Review
If you want a luxury SUV with jaw-dropping off-road chops and an image of bravado that few vehicles outside a tank can match, then raise a salute and stand at attention for the Mercedes-Benz G-Class (aka the G-Wagen). The 2018 G550 is a brute, but it also boasts amenities expected in a 6-figure Mercedes-Benz. AMG models (reviewed separately) notch up the insanity with high-performance engines.
Reality check: Do you really need an SUV with triple-locking differentials, 13-mpg combined fuel economy and the ride quality of, well, a vehicle designed for the military? We get the appeal of driving such an exclusive, luxurious beast. But a Range Rover, Porsche Cayenne or any number of upscale SUVs will deliver far more comfort for far less money.
