“Odometer Fraud. The contact owns a 1990 Cadillac Brougham. The contact purchased the vehicle from a dealer on eBay on 05/15/2025. The vehicle was shipped to the contact. The contact stated that when the vehicle was purchased, the Sales Agreement and the odometer indicated the mileage was 46,260. In addition, the contact stated that the Sales Advertisement indicated that the mileage was 46,260. The vehicle was taken to an independent mechanic for service. The contact was informed of several needed repairs. The contact then became suspicious of the odometer. The contact later acquired a Carfax report. The Carfax report indicated that in 2016 the vehicle received an Emissions Test, and the odometer reading was reported as 125,041. The contact then took the vehicle to Pep Boys, where it was confirmed that the odometer had been rolled back. The dealer was contacted several times, and the dealer was made aware of the odometer discrepancy. In addition, the dealer was made aware of the funds that the contact had invested in the vehicle for the repairs. The contact requested that all funds be returned, and the dealer take the vehicle back. The dealer ended communications.”
