These people are totally untrustworthy. Took my car in for a small A/C repair to replace a relay switch and he overcharged me. I didn't complain and paid as I was charged. I drove out and discovered the problem was not fixed. I had to take it back again and left it three days. When I went to pick the car up he charged me the same amount again for fixing a problem they failed to fix the first time. Found them to be unreasonable and unwilling to admit they failed the first time or negotiate a fair price on the second bill. I recommend you find an honest mechanic. There are other honest ones in town.
