2021 Mercedes-Benz C-Class Price Guide

The 2021 Mercedes-Benz C-Class (W206 generation) holds a strong position in the European used luxury sedan and estate market, with steady demand driven by its premium build quality, advanced tech features like MBUX infotainment, and efficient engine options including petrol, diesel, mild-hybrid, and plug-in hybrid variants. Current listings on sites like theparking.eu and AutoScout24 show prices heavily influenced by mileage (typically 50,000-100,000 km for 2021 models), body style (sedan vs. estate), and trim levels such as Business Line, Avantgarde, and AMG Line. Pricing trends indicate mild depreciation stabilization post-2022 supply chain issues, with popular diesel models like C220d retaining better value than petrol due to higher fuel efficiency demands in Europe. Demand remains robust in Germany, Belgium, and the Netherlands, where full service history and low mileage examples command premiums amid rising interest in hybrid tech.

2021 C-Class models have depreciated at around 12% annually from original new prices of €45,000-€60,000, now trading at 50-60% of MSRP after 5 years, with hybrids losing less due to eco-regulations. Diesel estates like C220d show slower drops (10-11% yearly) versus petrol C180 (13-15%), per listings on European auction sites. Best value emerges at 3-4 years old when initial steep depreciation flattens.

With EU emissions rules tightening, diesel and plug-in hybrid 2021 C-Class variants are poised for stable or slight price appreciation into 2027, while petrol models may soften 5-8% amid EV shifts. Rising used luxury demand and parts scarcity could support current levels, especially for well-maintained examples under 80,000 km. Economic factors like interest rates may pressure high-end AMGs, but overall outlook remains positive for mid-trim diesels.
