   41 of the same trim advertised at around 9,621 mi.

2. Mileage+12.6%$325K

   1,820 mi against 9,621 mi, the mileage the cars it is priced against carry. This cohort gives up 7.7% of its value each time the odometer doubles.

3. Specification+13.3%$368K

   This car has commissioned paint and 3 sought-after options. Most comparable adverts list no options, so they are read as cars without them. The paint is priced at the usual 12.0%: this generation has fewer than three cars either side of the line to measure it on. 2 of the 41 cars it is priced against are commissioned too, so the step against them is smaller.
