2006 F430

1. Comparable market$226K

   19 of the same trim advertised at around 21,048 mi.

2. Mileage+92.1%$435K

   1,330 mi against 21,048 mi, the mileage the cars it is priced against carry. This cohort gives up 25.6% of its value each time the odometer doubles. That curve was read off cars between 5,202 mi and 49,110 mi, and nothing has been observed beyond it, so the mark is struck at 2,601 mi rather than carried out to this reading. Confidence is low until a car near this odometer is advertised.

3. Specification-1%$430K

   This car has a manual gearbox. Comparable cars mostly do not.

4. Model year-0.1%$430K

   A 2006 against a cohort centred on 2007.

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