I just went through getting reamed by a shop.

I had this 1992 Caprice and the original rear end was howling. I installed a new police car rear axle with a better ratio. Ever since the wap I was chasing a driveline vibration. Long story short, After doing everything I could, I asked a friend who is a mechanic where to bring it. He suggested a local driveline shop and he sends all of his driveline work there.

I made an appointment and dropped the car off. I wrote a note about everything that was done so far and that if the repair goes over $350.00, to call me first.

First week: no word and when i called they were going over everything I already did.
Second week: no call and when I called they Did somethings and still not fixed
Third week: no call, when I called they talked about the pinion angle was off, ordered new control arms and the bill was $650. Shocked but still ok with it, I said go ahead
Fourth week: no call, I called and they said car is still vibrating and they are throwing in the towel. They were "not charging me for labor" and parts only at $950.00. I almost dropped the phone and started yelling at him. He said they went through the entire rear axle and have four weeks into the car.

I paid the bill on my unfixed car and I put it up for sale the next day. I couldn't even look at the car anymore. I will do everything in my power to cost them tripple that amount in lost sales.

If you are an honest mechanic, I will bend over backwards to be an awesome customer. Any MN residents want to know what shop it was PM me.
