Sell-or-hold analysis
Should I sell my 2023 Mercedes-Benz C 300 now or wait?
Compact luxury sedans have been one of the weaker residual segments in 2025-2026 as buyer demand has shifted heavily toward GLC and similar compact SUVs. The 60-day forecast below shows whether the C-Class can hold its current floor or whether segment pressure continues.
Mileage matters more on the C 300 than on most luxury sedans because the buyer pool is split between lease returns and individual private sales. Lease-return inventory under 36,000 miles dominates pricing — outside that band the dispersion widens significantly.

Common questions
Does the C 43 or C 63 affect base C 300 residuals?
Slightly — AMG variants pull enthusiast buyers out of the C-Class consideration set, which means C 300 buyers are squarely commuter/lease-replacement. That makes C 300 residuals more elastic to overall economic sentiment than to model-line factors.
Should I buy out my 2023 C 300 lease in 2026?
Compare the lease residual to the current 60-day P50 forecast below. If the forecast is at or below the residual, buying out makes financial sense only if you'd otherwise be in the market for a similar car. If the forecast is above residual, you're capturing instant equity.
Is the 2023 C-Class generation prone to early reliability issues?
The W206 generation introduced the MBUX 2.0 infotainment and 48V mild-hybrid system; both have had software-update cycles but no major mechanical concerns at this mileage band. Check that all manufacturer software updates have been applied at the most recent service.
