I got a CARFAX Report on a Subaru Impreza, and ended up buying it. The CARFAX was helpful and it let me know exactly what I was getting into. The car will require some mechanical work because of mileage, and the mechanics that looked over it for me pointed out a few items that will be needed. Along with the CARFAX Report, the dealer was up front with me on what was needed to be done to maintain the car past 200,000 miles. Overall, it was a very positive car buying experience.
