Things like mileage, season and condition are items that can greatly impact the amount of cash for car or truck properties that a driver might expect to get if he chooses to sell to a dealership or through a private sale. The lower the mileage on a car, the higher the resale value will generally be since mileage impacts so many types of wear and tear like tire strength, engine wear, and body condition. The season in which a driver decides to sell a car can also influence the price it can be sold for since convertibles sell well in summer and 4x4s sell well in winter.
