I bought my 1996 Impala after extensive use of CARFAX. I used it to evaluate price vs. mileage vs. car history. I was almost fooled by low mileage vehicles several times, but with CARFAX I found that a lot of those vehicles had improper odometer readings and were most likely rolled back.
Now I’m using CARFAX to sell my Highlander. Any time a possible buyer comes to check out my car, I show them the CARFAX Report to prove the legitimacy of the claims I’ve posted in my ads.
