The numbers
Where the price sits
Nothing else in the index is the same machine, so there is no honest number to measure this ask against. It is shown on its own instead.
A comparable is the same make, model, year and trim, within 3,999 miles of this odometer and 500 miles of this dealer. Unpriced listings are ignored, this one is excluded, and a dealer posting the same machine twice counts once.
