One-in-eight drivers (12%) have been charged more than quoted by garages for MOTs, services or repairs, according to a new survey. Just 3% of drivers say their final bill was lower than their initial quote. Overall, 59% of drivers say they’re worried they’ll receive an unexpected bill when they take their car to be serviced. Despite this, the majority of drivers polled said they are treated fairly by their garage.The report was published by RAC Garage Compare, which lets users shop around for garage services and review their experiences. RAC Garage Compare spokesman Pete Williams said: “Despite most motorists being reasonably satisfied with the cost of their bills, one-in-10 claim not to trust local garages at all while a wary 41% say they do ‘a little’ which doesn’t really seem like an overwhelming vote of confidence.“Even though we now live in a society which is obsessed with comparing prices for almost everything we buy, this behaviour has not become commonplace when booking a car in for an MOT, service or repair. This is partly because it had previously been a case of having to phone around to get prices and partly because there wasn’t an online service simplifying the process.Earlier this year, Auto Express Magazine found drivers face a postcode lottery when getting their vehicles serviced, with hourly costs as high as £141 in Twickenham, compared to just £44 in Orkney. The average hourly rate in the UK is £84.30.
