2015 918 Spyder

1. Comparable market$3.94M

   5 of the same trim advertised at around 655 mi, held toward the trim's quoted mark while the sample is thin.

2. Mileage-41%$2.32M

   41,187 mi against 655 mi, the mileage the cars it is priced against carry. This cohort gives up 13.1% of its value each time the odometer doubles. That curve was read off cars between 180 mi and 20,337 mi, and nothing has been observed beyond it, so the mark is struck at 40,674 mi rather than carried out to this reading. Confidence is low until a car near this odometer is advertised.

3. Specification+0.6%$2.34M

   Its factory options carry a small premium the comparable cars do not.

5 cars, model years 2015, asking prices spread ±37%.

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