2020 Mercedes-Benz E63AMG S

The asking price sits 138% above market—comparable vehicles are selling for a median of $42,000, meaning you're being asked to pay roughly $57,000 more than what this car is worth. Even accounting for mileage (29,000 miles is relatively low), the gap is indefensible. The vehicle's current book value sits around $50,000, which gives you a concrete floor for negotiation, but the seller is asking nearly double that.

Second, the depreciation curve is working against you. This car has already lost substantial value from its original price, and German performance sedans don't recover well. If you hold it for three years and add 10,000 miles as projected, expect further losses—you're not buying an appreciating asset here.

Third, ownership costs are steep. Annual maintenance runs $3,500 baseline for this model, and major repairs on AMG powertrains can easily exceed $5,000. You need to factor that into your total cost of ownership before committing.

The recall history is clean, which is the only genuinely positive signal in this analysis. But it doesn't offset the core problem: you're being asked to overpay significantly for a depreciating luxury sedan with high running costs.

Your next move: use the $50,000 BCV as your opening negotiation anchor and push hard toward $45,000-$48,000. Anything above $55,000 is difficult to justify based on market data.
