I bought a Vauxhall Corsa from new, to keep it under guarantee I had to get it serviced at an authorised garage. Fair enough.
However there was not one service below £230, I did a lot of mileage but it was only the usual stuff, oil change and wiper blades etc.
One service cost £580 after the car was 2 years old - all it was was the service, some new wiper blades and two brake pads. I got in my car to find a greasy hand print on the ceiling.
Despite some pretty heavy complaining I still ended up footing the bill. I'm starting to get more wound up by the times I have given in to things like this by shrugging my shoulders and handing over my debit card.
I don't mind paying more for good workmanship - but I feel this was way above what it should have cost and the only reason was I was tied in to their garage to keep the guarantee valid.
