2018 Mercedes-Benz E63AMG S

The numbers tell a clear story. The median comp price sits at $42,000. The wholesale estimate (what you'd get selling it quickly) is around $43,000. The asking price is nearly double both. Even the BCV—the estimated current value accounting for condition and mileage—comes in at $50,000. No matter which valuation method you apply, you're looking at a $30,000 to $38,000 gap between what the seller wants and what the market will bear.

That gap matters because it compounds your downside. You'd be buying into an immediate $21,944 loss against the BCV alone. Over a holding period, depreciation will continue—this car has already shed significant value from its original price. Add in the annual maintenance costs of $3,500 (this is a high-performance specialty car), and your total cost of ownership becomes steep relative to the asset's trajectory.

The one bright spot: no open recalls and a clean safety history. The dealer shows no red flags either.

But here's what you need to do next: get a pre-purchase inspection from an independent Mercedes specialist. The asking price suggests either the seller is disconnected from market reality or there's something about this specific car's condition or history that isn't reflected in the data. An inspection will tell you which.
