The Renault Megane tops a chart compiled by the BBC using Department for Transport data that identifies the cars that most frequently and infrequently failed their first MOTs in 2007.
The data, issued by DfT subsidiary the Vehicle and Operator Services Agency, reveals that 28.1 per cent of all ’53-, ’04- and ’54-plated Meganes which underwent their first MOT test in 2007 failed that test.
That compares with 24.7 per cent of Peugeot 307s, which is identified in the data as the joint second most likely vehicle to fail an MOT at that age. The Vauxhall Corsa ranks joint second at a 24.7 per cent failure rate, while the Renault Scenic charted fourth with a 23 per cent failure rate.
The vehicles that proved least given to failing their first MOT in 2007 were the Toyota Corolla (11.2 per cent), the Honda Jazz (13.3 per cent) and the Honda Civic (14.1 per cent).
The data was issued under a Freedom of Information request submitted by the BBC, which has this morning collected it into a list and published it online.
The BBC’s list, however, includes only those cars that were tested 20,000 times or more in 2007.
A Renault statement said: "In 2004, the Renault Mégane was the second best-selling car in its segment, with a majority of its sales to company fleets. These vehicles will do an above-average mileage and it is unfortunate that the data does not take this into account as there are a multitude of reasons why a vehicle can vehicle can fail an MOT, from a light bulb to a tyre, that relate to use and maintenance. "Also we do not understand the 20,000 threshold for the data that has been provided by VOSA, as there are a number of vehicles below that with a higher failure rate."
