Those dicks nickel and dime everything. If a part has a bracket on it, they charge for that. Environmental fees, all sorts of BS tack on charges. It is almost as if it is a business.
Seriously though...they are dicks about the added charges.
I'm surprised to see that you were able to get the brakes from the car. That stuff usually is the first to get grabbed. The car must have just landed in the yard. Good for you, man!
