RPM Auto Repair

I had my mother bring her car to this shop and relayed to them what she had told meUnfortunately since I was inquiring about what all the expenses were and what exactly they were doing to the vehicle they decided not to work on itThis tells me that they were likely going to try to get some free money out of this since I myself know a bit about carsThey charged $just to hook the car up to a computer, most places offer this for free, and then told me it was going to cost $to diagnose further just one of the issues before they'd do any workMy primary issue is that I am knowledgeable about cars and when asking for details they got nervous and declined to work on my mother's vehicle
