We were looking hard for our son's first car. We were looking at old Toyota Corolla's no more than about 150,000 and of course older years. We were willing to spend about $2500 if it all checked out Seemed like all privately owned good deals went within hours. We would pull them up on autotrader or craigslist or cars.com. We finely got one off Craigslist, called for an appointment and we were the first ones to see it. The man said he had several staggered after that. It was like 1996 Toyota Corolla with about 150,000 for about $2500. It was already smogged. We went down, test drove the car, ran smooth seemed great and didn't have time to run a Carfax or deal with the price. We ALWAYS would run a Carfax! After the test drive 3 people showed up and my husband had to make a decision to buy it as the next people were ready to grab it. It was my son's first car and it seemed clean and ran well. A few weeks later he started mentioning some things were loose on the dash and the car was running rougher. After a month I happen to be driving it and realized it was running like garbage and the dashboard around the guages was loose. So my first instinct was to run the Carfax and sure enough the last mileage 8 months before the sale of this car was 200,000 miles. And after that it showed the smog test and our purchase with mileage reading 150,000 approximately and a note by CARFAX MILEAGE DOES NOT MATCH. I immediately called DMV. It was definately tampered with but I asked if could we go and get our money back and they said absolutely it was up to us. They would deal with the odometer tampering. We had it smogged and checked the box on the title that mileage did not match as they instructed. We went to his home and left a note on his door stating he tampered with the mileage and it was illegal and we wanted our cash back. Unfortunately he was American Colombian and out of the country and his poor wife was left to deal with this. She had no idea. So we were polite and she gave us the cash back and we gave them back the title with the box checked, mileage doesn't match. He told her on the phone for us to leave it blank. But of course we didn't so he is unable to sell it to another unsuspecting person without disclosing the correct mileage. And of course the DMV had him on odometer tampering. We have since bought my son a car and first thing we do is run a Carfax. We did run into other people lying about mileage and we confronted them with the carfax report. I have never bought another car without a Carfax! Sorry a bit long but it's a life saver! There are some pretty scummy people out there! Thanks CARFAX!
