The garage said the parts would arrive this morning. They have told me ican pick it up this afternoon. The parts costs are around 60 pound leaving 690 pounds to fit the parts in one morning. This seems excessive. What rights have i got to query the bill.
I agree with you that £690 for what amounts to a morning’s work appears to be grossly overpriced but that depends on how much work was done previously to get to the root of the problem.
However what may happen in this situation is that they may refuse to return the car to you until you pay the bill. If that happens the quickest way to resolve this is to pay the bill in full on the basis that you paid it with no alternative and under pressure. What you then do is ask them for the overcharge back and if they don’t pay to you, sue them to get it back to the Small Claims Court.
Here is the link to the Small Claims Court track for you.
Can I clarify anything else for you?
