2018 Mercedes-Benz E63AMG S

Here's what the numbers tell you. The asking price sits $2,000 below the median comp at $42,000 and $10,000 below Black Book valuation of $50,000. That's aggressive positioning that suggests either motivated selling or a vehicle with undisclosed issues—you'll need to verify which. The market itself is signaling "strong sell," meaning inventory is moving and prices are firm, so this discount is real opportunity.

But here's the catch: this car costs roughly $3,500 annually in routine maintenance, well above luxury sedan norms. Over a five-year ownership window, that's $17,500 in upkeep alone. The depreciation curve also shows the E63 AMG S trades at historically steep discounts—you're currently buying at 41.7 cents on the dollar relative to original MSRP. That trajectory matters if you're planning to sell.

The good news is the recall history is clean, and there's no dealer red flag suggesting financing manipulation.

The single most important thing you should do next: get a pre-purchase inspection from a Mercedes specialist, not a general mechanic. Given the maintenance costs and the aggressive pricing, you need to know exactly what deferred service or mechanical issues might be hiding. That inspection will tell you whether this discount reflects genuine market opportunity or upcoming repair bills.
