Used Mazda trucks are available from eBay, Kelley Blue Book, Car Gurus and Carfax; each website has tools to make an informed purchase. Carfax offers history reports on cars based upon a vehicle identification number. Reports include prior registrations, damages and odometer rollback fraud among other things.
Kelley Blue Book offers a service that determines a used car's approximate value based upon various factors such as mileage and condition. The valuation by Kelley Blue Book is a free service, while Carfax charges a fee for its service.
Cars purchased on eBay carry a vehicle protection program that covers any vehicle purchase up to $50,000 from fraud or inaccurate vehicle descriptions, as of 2015. The other three websites only host classifieds and accept no liability in purchases.
