As many as six in 10 motorists (59%) claim to worry about hidden costs when booking their car into a garage for an MoT, service or repair.

Research carried out by RAC Garage Compare found almost a quarter (24%) of those who admit to being fearful, describe themselves as being ‘very concerned’ of unexpected ‘extra’ charges.

For  more than one in 10 (12%) they say their bills end up being more expensive than the garage said it would be.

More than half of the motorists (51%) surveyed rate local garages as being ‘good’ in terms of the fairness of their pricing whereas only 5% class them as being ‘bad’ and one in three (28%) believing them to be ‘ok’.

Nearly a third (31%) of those surveyed felt it would be very useful to be able to compare upfront garage prices for MoTs, services and general repairs before booking.

An RAC Garage Compare spokesman said: “Despite most motorists being reasonably satisfied with the cost of their bills one in 10 (11%) 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.”
