Very disappointed. I took my car in because it was running rough, paid them $100 to run an analysis. They called and said a part needed replacement and would cost an additional $340. Naturally, I went online to see what the usual cost for that would be. -Repair pal- gave an estimate at between $160 and $220 for my area NOT $440. I told them no thanks and on my way home from Superior Automotive I stopped at the auto parts store, bought the part for $80 and had it switched out within the hour. The car runs great. These people are a total rip-off. How often do they stack the bill? I will never go there again and will steer as many people clear of that place as I can!
