Depreciation: retaining value in the luxury market

Luxury vehicles generally depreciate faster than non-premium brands, due to higher initial prices and rapidly evolving technology. However, Mercedes-Benz models tend to retain value better than some rivals if well maintained. Classic and specialty models—such as the G-Class, the SL roadster, and AMG performance variants—sometimes appreciate over time or hold their value exceptionally well due to demand among collectors and enthusiasts.

Performance and driving experience

One area where Mercedes vehicles consistently shine is performance. Mercedes-Benz engineers vehicles to deliver a refined and engaging driving experience, blending comfort with power. The company’s AMG line, in particular, is revered for producing some of the fastest and most exciting sedans and SUVs on the market.

Handling and comfort

Most Mercedes models are praised for their smooth ride quality, quiet cabins, and responsive handling. Adaptive suspension systems allow drivers to customize ride settings for sportier or more comfort-focused driving. Long highway trips, in particular, are where Mercedes-Benz vehicles excel, offering a plush experience compared to many other luxury cars.

Engine options and technology

Advanced engine options, from fuel-efficient turbocharged four-cylinders to V8 and V12 powerhouses, give buyers a wide range of choices. The brand also invests heavily in hybrid, plug-in hybrid, and electric technology, with its EQ line targeting environmentally conscious consumers without sacrificing performance or comfort.
