Shaker Auto Hospital

My car had engine light on, so I brought it to the Shaker Auto Hospital for diagnostics. Mark tells me that I will need a new throttle body that will cost $1,500. I approved that, but requested my old part back. A while later Mark calls and says that I don't need the new throttle body after all. Says that they changed the coolant & antifreeze and the light went off. Hmmm On a prior occasion, Mark mentioned that one of his mechanics owns the same car as mine. I am not accusing anyone but can't shake it off. One heck of a coincidence, what would have happened had I not requested the old part back? Likely coughed up $1,500, that's what I am thinking. Following repairs, my car was kept in the shop for several days while being taken on a road test, whatever that means. Used up a quarter tank of gas. About a month later I went to another place for an oil change, and they weren't able to do a tire rotation because the wheels were overtightened. The only other place I had my car in prior to that, was Shaker Auto Hospital. I don't know if this is a common practice to over-tighten the wheel lugs but this will result in yet another repair bill. It could have caused a huge problem per chance I happen to have a flat and no one would be able to take a wheel off. Bottom line, I don't recommend Shaker Auto Hospital especially for the extensive repairs or for the turbo cars. I am not going to set my foot in that shop for the rest of my natural life.
