2017 Mercedes-Benz E63AMG S

Here's what matters most. First, the valuation gap is substantial. The median comparable price for this model is $42,000—meaning you're being asked to pay a 71% premium over what identical cars are actually selling for. Even the Black Book Value (BCV), which accounts for condition and mileage, sits at $50,000. You're $22,000 above that baseline. Second, the depreciation math is working against you immediately. Current market value is estimated at $58,056, which means you'd start $13,944 underwater on day one. This isn't a car that's going to appreciate or hold value—it's going to continue depreciating, and you're buying in at an inflated entry point. Third, the ongoing costs are real. Plan on $3,500 annually in routine maintenance for this AMG variant. That's $290 monthly just to keep it running properly, which compounds the financial strain of an already overleveraged purchase.

The market direction is explicitly negative (score: -0.5), and the negotiation intel confirms the seller is significantly disconnected from reality. With 29,000 miles on a 2017, this should be a reasonable acquisition—the mileage is actually favorable—but the asking price negates that advantage entirely.

Your next move: Get a pre-purchase inspection from an independent Mercedes specialist, then use that report as leverage to negotiate down toward the $50,000 BCV range. Don't proceed at the asking price.
