I use CARFAX on every car, I purchased three cars in the last two months for our granddaughters, usually the dealers web site I can check the CARFAX. I do not do the autocheck or what ever its called. Yesterday I called a dealer about 50 miles away about thee last vehicle I did purchase but when I asked about the CARFAX he did not want to do it so I said no sale, at that point he did do a CARFAX. When I went to do the paper work he added 39.00 dollars to the bill, which I said I can do the same online, do you want the deal or not they took it off. Thanks for the great details and peace of mind with CARFAX
