How this is built: a price-vs-mileage curve fit to 0 dealer sales (thin). Weissach, color, condition and history adjustments are starting assumptions until we have enough tagged sales to measure them. Auction fees are Bring a Trailer's current schedule (buyer pays 5%, capped at $7,500). This is an estimate, not an offer.

Auction results

The 3 most recent Grand National auctions across Bring a Trailer, Sotheby's Motorsport, Bonhams, Barrett-Jackson and Hagerty, from Old Cars Data. Hammer prices are what the car actually sold for; reserve-not-met rows show the high bid.

Generation	Auction sales	Auction median	Their median miles	Dealer median	Dealer miles	Gap
all	2	$56,625	32,350	$0	0	+Infinity%

Read the gap with care: most of the all auction cars were Weissach-package cars, and a few auction results per generation is a small sample. The 991 cars come in 5 to 7 percent under dealer asks at similar miles, roughly the room you'd expect between a dealer's asking price and a hammer price. The 997.1 figure is a single 33,780-mile car and says little about the generation.
