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 C-Class
KBB.com Review
Kbb.com Expert Rating
Whether you’re drawn to its craftsmanship, elegant styling, technology or coveted German badge, the Mercedes-Benz C-Class remains the entry-level luxury car to which others aspire. The C-Class even offers high-performance Mercedes-AMG models (reviewed separately) and a plug-in hybrid version called the C350e.
The C-Class’ features and enviable reputation come at a price that starts higher than those of its rivals. If you want a compact luxury car that’s as distinctive as it is practical, you might like the roomier Audi A5 Sportback or BMW 4 Series Gran Coupe.
