2018 BMW M6Gran Coupe

The core problem is valuation. Comparable M6s are selling for a median of $26,200 right now. You're being asked to pay 79% more than the market will bear. That's not negotiation room—that's a fundamental pricing disconnect. The car's book value sits at $35,000, meaning you'd be overpaying by $11,999 even if you got the seller down to that level.

On the positive side, this M6 has clean history: no recalls, low mileage at 29,000 miles, and it sits in the sweet spot of the depreciation curve where performance cars stabilize. That's genuinely valuable. But it doesn't justify the premium you're being asked to pay.

The real concern is what you're not seeing. The dealer's reputation is completely opaque—no ratings, no review count, no franchise status on file. Combined with an asking price this far out of line with market reality, that's a red flag. You're also looking at $3,500 in annual maintenance costs once you own it, which is high-tier territory for a performance sedan.

Before you engage further, get a pre-purchase inspection from an independent BMW specialist. That will tell you whether the vehicle's condition justifies any premium at all. But realistically, you need the seller to come down significantly—closer to $30,000—before this becomes a rational purchase.
