Was searching online for a Jeep Wrangler...After weeks of searching the internet, I found the perfect Jeep......Seller had no CarFax. So I signed up for unlimited carfaxs for a month, just in case I needed to find another Jeep. I signed in with the car lisence plate and in a couple minutes found that the odometer had been rolled back 40,000 miles. I notified the owner who had no idea since it was rolled back in 2010 and she had purchased it in 2013...Told the owner I could't buy her Jeep, as it would be difficult for me to sell later with this problem...I was very disapointed, but 2 days later found a much better Jeep for $2000 less. I'll never buy a used car again without a CARFAX........... Thanks CarFax for saving me $2000, plus avoiding a major problem............ R.D. Smith Indio, Ca.
