A recent investigation has revealed that about 20 percent of used cars available for sale have a history of significant damage that often goes undisclosed to buyers. The study, conducted by CarVertical, analyzed tens of thousands of second-hand vehicles in 2025 and found that many of these cars had undergone repairs costing an average of £4,800, yet this information was rarely mentioned in sales listings.
CarVertical gathered data from insurance claims, repair shop records, and vehicle inspections to uncover the hidden damage histories. Their report shows that some car brands are more prone to having undisclosed damage than others. Vauxhall topped the list, with nearly a quarter of its checked vehicles showing at least one major damage event. Other brands with high rates of hidden damage include Fiat, Seat, Hyundai, and Ford — all popular choices among budget-conscious drivers.
Smaller cars, especially supermini models often favored by younger or city drivers, were most likely to have undisclosed damage histories. The Seat Ibiza was the model with the highest percentage of damage reports at 33.6 percent, followed by the Audi A1 and Fiat 500. These findings highlight the risks buyers face when purchasing affordable used cars that may have suffered accidents or structural harm.
The financial impact of such damage can be substantial. While some repairs are minor, others can be severe enough to classify a vehicle as an insurance write-off if repair costs exceed half the car’s market value. Luxury brands like Bentley and Tesla had some of the highest average repair bills, reaching up to £16,000 for Bentleys and nearly £6,000 for Teslas. Despite this, many damaged cars still appear on the market without clear disclosure of their past issues.
Experts warn that while a history of repairs does not automatically mean a car is unsafe, it should prompt buyers to examine vehicles more carefully. Poorly done or rushed repairs can lead to future problems that are difficult to detect during a simple test drive. Buyers are encouraged to request detailed vehicle history reports and pay special attention to areas where damage was previously recorded.
CarVertical’s spokesperson emphasized that hidden damage is one of the most common challenges in the used car market and affects many popular models chosen for daily use. The lack of transparency particularly affects private buyers who do not have the same protections as those purchasing from dealers who are legally required to disclose known damages.
This new evidence serves as a reminder for prospective second-hand car buyers to remain vigilant. Checking a car’s full background can help avoid unexpected repair costs and ensure safer purchases. The findings underline the importance of comprehensive vehicle inspections and transparency in used car sales to protect consumers from hidden risks.
