For many used-car buyers, discovering a manipulated odometer is a financial setback they are rarely prepared to address. A comprehensive study by carVertical found that 75.8 percent of European drivers would not know where to report a vehicle with falsified mileage. Another 87.3 percent have little or no confidence they could recover their lost money.
Spanish buyers face similar challenges. Between September 2024 and August 2025, carVertical’s Market Transparency Index found signs of odometer rollback in 3.25 percent of Spanish vehicles checked on the platform. When fraud was detected, the average rollback was 89,400 kilometers, significantly distorting a car’s value and maintenance history. The European Commission estimates that odometer fraud causes annual losses of around 9.6 billion euros across Europe, with cross-border used-car sales particularly vulnerable. Diario de Avisos has reported that about one in twelve used cars in Spain may have a manipulated odometer; in the first seven months of 2026, 2% of checked vehicles showed mileage discrepancies. Without a unified European mileage database, fraudsters can more easily exploit cross-border vehicle sales.
The problem extends beyond the fraud itself. Nearly a third of respondents across 18 European countries said they had personally bought a car with a manipulated odometer or knew someone who had. Another 31.8 percent were unsure whether they had encountered such a vehicle, while only 38 percent were confident that neither they nor anyone in their circle had been affected.
Legal recourse is often unclear. Spain has no law specifically targeting odometer tampering, but deliberately altering mileage for profit can be prosecuted as fraud under Article 248 of the Penal Code. Still, 45.1 percent of surveyed buyers did not know the maximum penalty, and 7.1 percent believed the practice was not illegal. Only 28 percent recognized prison as a possible consequence, while 19.8 percent mentioned a minor fine. In total, 72 percent of participants failed to correctly identify the legal risks associated with this type of deception.
After fraud is discovered, most buyers are left without clear options. The study found that 43 percent have no faith in recovering their losses, and another 44.3 percent have little confidence. The lack of clear reporting channels and fragmented vehicle histories, especially for cars that have crossed borders, make it even harder for consumers to take action. As Matas Buzelis of carVertical notes, legal rights are of little use if buyers do not know how to exercise them.
Buyers can take several steps to guard against odometer fraud. Checking the dashboard reading alone is not enough: mileage should be cross-referenced with available records, including maintenance invoices and inspection reports. Excessive wear on a steering wheel or seat that does not match the declared mileage should raise suspicion. The study also points to the need for better information sharing between European countries, since fragmented records make fraud easier to conceal when vehicles cross borders.
Before finalizing a purchase, experts recommend verifying the car’s history and comparing the declared mileage with multiple sources. This may reveal inconsistencies before money changes hands. For further context on automotive industry risks, the recent recall of over 183,000 vehicles in China due to safety concerns shows that transparency and consumer protection remain pressing issues across the sector.
Odometer fraud leaves buyers exposed and with limited support. Unclear reporting channels and fragmented vehicle records, compounded by limited legal knowledge, create conditions in which deception can thrive. Until authorities and industry players address these gaps, used-car buyers will continue to shoulder the risk, often with little hope of justice or compensation.
