1. Comparable market$485K

   19 of the same trim advertised at around 15,573 mi.

2. Mileage+112.9%$1.03M

   527 mi against 15,573 mi, the mileage the cars it is priced against carry. This cohort gives up 27.8% of its value each time the odometer doubles. That curve was read off cars between 2,221 mi and 88,887 mi, and nothing has been observed beyond it, so the mark is struck at 1,111 mi rather than carried out to this reading. Confidence is low until a car near this odometer is advertised.

3. Model year-8.2%$949K

   A 1998 against a cohort centred on 1999.

19 cars, model years 1997–2001, asking prices spread ±16%.

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