2018 Mercedes-Benz S-class S 450 4MATIC 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 Mercedes-Benz S-Class
KBB.com Review
You know you’ve arrived. If the rest of the world hasn’t caught on, they surely will when they see you in a new S-Class. This flagship Mercedes is a rolling testament to monetary success. Aside from prestige, the 2018 S-Class remains a fantastic car both to drive and to be driven in.
If the S-Class’ nearly 6-figure cost gives you pause, you might consider the all-new Lexus LS, Genesis G90, Acura RLX or Volvo S90, all of which can be had for far less. The S-Class’ archrival BMW 7 Series also begins about $10,000 less. Also all-new is the Audi A8, which promises a higher level of self-driving capability.
