car fax sucks. the whole business model is based on extortion. google carfax complaints it will quickly become apparent how they operate. the best thing you can do before buying a used car is take it to a shop you trust to have them give it an unbiased inspection. i tell our customers that i can't guarantee they will buy a good car, but i can guarantee they won't buy a bad one.
also doesn't this forum have an off topic section?
