What is my 928 worth?
Enter your car and we'll estimate its market value from the dealer and auction sales on this page, then show what you'd walk away with at auction, selling to a dealer, or listing it yourself.
An auction would net only about $NaN more than a dealer offer, which isn't worth the weeks of waiting and the risk of a no-sale. Take the dealer's money.

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 15 most recent 928 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 | 11 | $16,928 | 92,000 | $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.
