I was searching craigslist for a used Mazda Mx-5. Being that they are, by nature, a car-tinkerer's wet dream, and craigslist is a minefield of garbage, I needed some form of vehicle history reports. I bought one report initially, and the news was good.. Until the person I was looking to buy from sold the car as I was on my way to go buy it. I went back on the hunt and equipped myself with the unlimited reports package (ALWAYS GET THE UNLIMITED PACKAGE). After slogging through a dozen or so miata carfaxes that had problems I wouldn't have otherwise known, I finally found one that seemed to be worth a look. I went to go look at it, and decided I needed to buy it. Carfax showing that NONE of the maintenance had been reported saved me the money I spent on reports and then some. Thank you carfax!
