I spotted a car on Craigslist with 131,973 miles. I goggled the VIN and found out the car was recently sold at auction with 206,044 miles. What would you do about it besides not buying the car? It must be very common scam in used cars, especially when there are few owners, hard to trace mileage on carfax. I recently test drove a car with "87000 miles" that looked and felt like 287000 miles. Apparently the digital odometers are easy to roll back.
