How this car is valued

RevFolio holds 26 completed sales of the Porsche 928 928 GT from 1989 to 1991, inside a Porsche 928 book of 145, dated Oct 04, 2016 to Aug 11, 2026. Across the whole 928 book, when each sale was hidden from the engine and valued on the sales before it, 56% came within 20% of the real price.

The engine keeps gearboxes apart where the sales show they price apart, reads each listing for disclosed damage, modifications and conversions, fits a mileage curve on the matched sales and weights the newest sales most. Every report prints the sales it used.

Every generation and variant: the Porsche 928 page.
