1. Comparable market$579K

   3 of the same trim advertised at around 15,705 mi, held toward the trim's quoted mark while the sample is thin.

2. Mileage-9.5%$524K

   71,970 mi against 15,705 mi, the mileage the cars it is priced against carry. This cohort gives up 5.9% of its value each time the odometer doubles. That curve was read off cars between 3,062 mi and 27,097 mi, and nothing has been observed beyond it, so the mark is struck at 54,194 mi rather than carried out to this reading. Confidence is low until a car near this odometer is advertised.

3 cars, model years 1983–1996, asking prices spread ±62%.

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