1. Comparable market$481K

   5 of the same trim advertised at around 22,698 mi.

2. Mileage+21%$582K

   3,062 mi against 22,698 mi, the mileage the cars it is priced against carry. This cohort gives up 9.5% of its value each time the odometer doubles. That curve was read off cars between 8,495 mi and 71,970 mi, and nothing has been observed beyond it, so the mark is struck at 4,248 mi rather than carried out to this reading. Confidence is low until a car near this odometer is advertised.

5 cars, model years 1992–1994, asking prices spread ±37%.

Struck from advertised cars and adjusted to this one. Indicative only.
