alighn, Belts, valves covers

Double check everything they do. 1st car was simple alignment. Got in and steering wheel 1/2 turn out. Had to go back. Total time was over 4 hours spent. 2nd car I had belts changed. Within a week they were squealing. Took it back and no problem they fixed it and CHARGED ME $40. What? Didn't tighten them correct first time! 3rd car valve covers were leaking oil. PAID TO CHANGE THE PAIR. picked it up got home and noticed oil LEAKING on driveway. Guess what. They only changed one and charged $400 for two. Took it back. More time spent. I was told they did both but would fix it anyway. New story was somebody turn the valve cover around. SOMEBODY? NOW THEY BLAME SOMEBODY ELSE! don't forget I paid for 2 and got 1. OK they fixed it and got home and 2 days later leaking oil again! FOOL ME TWICE SHAME ON YOU. FOOL ME 3 TIMES I MUST HAVE BEEN CRAZY. Stay away. They cannot be trusted.
