Mostly I have found these guy's to be competent at their job.However on 1 occasion we had a problem when the mechanic couldn't diagnose the problem and suggested we replace plugs and hoses at a cost of approx $300 to us, only to find out that wasn't the problem at all.NOT HAPPY AT ALL!!!!! Then didn't know what was wrong and had no other ideas.We took the car to AUTO centre on Sherriffs Rd he diagnosed the problem immediately .Taking your car to the manufacturer you expect the best and in this case we didn't get it.
