As expected, there is an inverse relationship between the price of the car and the mileage: The higher the mileage the lower the price.
However, the study noted an interesting trend. Look at the vertical bars along the horizontal axis representing the mileage at 10,000 mile increments. Notice the drop off in the price of the car RIGHT AT the 10,000 mile increment (arrows pointing).
If the mileage is just short of the 10,000 mile mark the vehicle gets a significantly higher price than if it has 100 or so additional miles OVER the 10,000. Otherwise the relationship is pretty smooth BETWEEN the 10,000 mile increments.
If you want to get the highest possible price for your car, given its mileage, the best time is to sell it BEFORE it rolls over the the next 10,000 mile mark. Otherwise you will be out some money! If you are a buyer then look at cars that just cross the threshold.
There is one interesting point on the graph. Look at the RED arrow. At the 30,000 mile mark the pattern is noticeably interrupted. There appears to be no price "cliff" at that threshold.
Any guesses as to why (1) the noticeable drop off in prices at all but one (really more at the very high mileage level) of the 10,000 mile increments, and (2) why the absence of one at 30,000 miles?
