So, you're saying that you wouldn't get a 2nd opinon if you took your car in for repair and after much $$$ in parts and labor your car's problem is still there?
Maybe you wouldn't...
Maybe you have so much money that you will just keep throwing it at people not caring on how the money is spent. But most people can't afford that.
I think if this is any other shop, with the same story, it will sound just as bad. At least to me.
