Like everyone else, I was look for an extraordinary automobile bargain that was not only reliable, but also satisfied a fairly narrow set of desirable criteria for the car I wanted to buy. Initially, the super-wide selection available on the internet from Cars.com, KBB, Motor Trend, Car and Driver, Ebay, Amazon, etc., etc. etc.; was overwhelming in its magnitude. CARFAX was the singularly most informative, trusted and user-friendly tool available. The ability to track the history of repairs, accidents, repairs, mileage and emissions testing of each car helped me whittle the list of potential purchases down to four really excellent local choices. When I located the best of those choices; a mint-condition, low-mileage, scrupulously-serviced, loaded with every factory and dealer option except surround sound, 1999 Volvo V70 XC in my favorite color for under $3000 ($2490); I was ecstatic!! And when I was able to get an additional $100 off because the CARFAX report informed me that it had been in the dealer's back lot for the last three months, I was fully satisfied I had gotten the best deal I have ever experience in all my 45 years of car buying. I had happily paid $2500 in 2000 for a low-mileage, well-maintained 1981 Volvo 245dl that originally sold for $12,300 new. Paying $2,390 for this pristine 1999 V70 XC that originally sold for $38,000 new would not have been possible without CARFAX. The $60.21 (including sales tax) I paid for the unlimited CARFAX reports option saved me from having to spend $100-300 per vehicle to have them properly inspected. The only improvement i can think of is that there should be no limit on the number of reports you can get using the VIN for identification. Getting the license number for used cars over the phone can be a very time-consuming and grueling experience.
