Hi, I put my ute into the mechanics for a service this morning, it was running fine. Picked it up this afternoon and my ute now has no power and can't go past 40kmph. It's virtually undriveable. The mechanic has advised that it was a coincidence that the turbo has packed it in while they had it. Basically what I need to know is do I have a leg to stand on to ask them to fix it at their cost? Thanks.
