Pricing Out Some Auto Repair in Orange County

When I bought an older, used car I knew that eventually I would need to have some things done to it. I have gotten a lot of use out of my car but it now needs work. I have been pricing out auto repair Orange County. Unfortunately the work that it needs done is a major repair. I want to make sure that I get the best price on the work that needs to be done. I have taken it to a few places already and think I know the range that I am going to pay. I just want to make sure.
