Hi Anne. When there is only one owner previous for a used car, we would know about all the modifications or lack thereof done to that car and how well it has been taken care of because we can get that information from this one owner. Contrast to a car owned by 6 people before, there's no saying what the previous owners could've done to modify on the car and contacting all 6 of them to ask about the car is not really feasible. In the event of a break down the latter car would have much higher complications due to the high number of unknown modifications. So generally the number of owners do affect the pricing of certain vehicles.
