2018 Mercedes-Benz E63AMG S

The asking price sits $1,000 below the median comp at $42,000, which sounds like a bargain until you look deeper. The car's book value is $50,000, meaning you're $9,000 under what the market actually values it at. That gap doesn't reflect a negotiation win—it signals something is wrong. The deal score of -0.5 out of 100 confirms it: this pricing is a warning, not an opportunity.

The second issue is maintenance. You're looking at $3,500 annually in upkeep costs for this twin-turbocharged AMG variant. That's roughly double a standard luxury sedan. Over five years of ownership, that's $17,500 in maintenance alone—money that compounds the risk of buying a car already priced suspiciously low.

The one bright spot: the car has no open recalls and carries only 29,000 miles, suggesting low use and potentially fewer hidden problems. But that doesn't offset the pricing red flag.

Before you proceed, get a pre-purchase inspection from an independent Mercedes specialist. The asking price relative to book value suggests either undisclosed damage, mechanical issues, or title problems. That inspection will tell you whether this discount reflects reality or if the seller knows something the market doesn't. Don't negotiate on price until you have that answer.
