The best thing to do here is get a break down of your total cost for the repair. Get the price for each repair separately. If you have taken your car in for several different things, have the shop break down each cost of the items. Let's say you took your car in for an oil leak and belt squeak noise. The shop tells you it is a front cover seal is leaking, and a pulley for the belt system is bad. Then you get a total cost of $500 for all the repairs.
