Getting a lien search and/or a vehicle history report is important to get BEFORE you make an offer to purchase.
CarProof searches vehicle records in Canada and the US. Includes information on whether vehicles have been stolen, rebuilt, salvaged or written off. The report also contains Canadian lien information.
CARFAX searches records in Canada and the U.S., with a focus on American information. It's especially important for Canadians thinking of buying a used vehicle from the United States.
