I was in the market for a early 2000's honda accord. I had reviewed several websites, sale by owner. One, in particular, had advertised the car as a 2002 Honda with a 4 cylinder v-tec engine, the exact engine that I was hoping for. I sent a text message to the owner and asked to see the vehicle. We made an appointment for later that afternoon. I reviewed the post again and decided that before I went to the appointment I should go check the CarFax. I had been looking at so many cars online that I decided to get the "unlimited" option. I downloaded the license number, another great CarFax option, and the car information popped-up. To my surprise, the car was not a 2002, it was a 2001. The engine, the most important thing I was looking for, was not a 4 cylinder v-tec, but the more unreliable and gas hungry 6 cylinder. Needless to say, I contacted the owner and cancelled the appointment. That afternoon, I found another car online. Before I even contacted the owner, I accessed my "unlimited" CarFax and got all the information. One of the most important things that it demonstrated was the service record, which fortunately was noted as being from the local Honda dealership, a dealership know for good workmanship. The car was thirteen years old, and CarFax had its entire history right there in black and white. I made the appointment. The owner showed up with all the maintenance paperwork and needless to say it matched almost to the letter with the documentation found on the CarFax. I am a believer. Next time I am looking for a car, I simply won't waste my time...I will get the CarFax.
