New research has highlighted the vans on UK roads that are most likely to have a recorded mileage discrepancy.

The study, by Rapid Car Check, estimates that almost 2.5 million cars and vans in the UK have a recorded mileage discrepancy based on a sample size of 4m vehicles.

This is caused when the recorded mileage drops between MOT tests or if there is a mixture of odometer reading in miles and kilometres.

Almost 6% of vehicles checked were highlighted for having a negative mileage variation between MOT tests, suggesting the mileage was altered or the odometer was replaced between tests.

The Citroen Dispatch was found to have the largest mileage discrepancy, with 31% of 4,373 vehicles checked failing the Rapid Car Check test.

As the most popular LCV in the UK, more than 8,700 of the 77,500 Ford Transits checked were found to have a discrepancy.

As this study only looked at recorded mileages at the time of the MOT test, it does not account for vehicles that were clocked prior to a test, such as those that are less than three years old, and therefore does not give a truly accurate representation of clocking.

In a previous study carried out by Rapid Car Check, the company found that, on average, vehicle mileages were reduced by 70,000 miles in the cases where discrepancies were found.

Only vehicles with more than 1,000 ‘fails’ were included in the data, which can be viewed here.
