I have used click mechanic 3 times. My experience is that for basic things like servicing they are ok and competitively priced and reliable. That's how they seem to hook you in. However, on 2 occasions I have asked for a quote for additional work. This results in a diagnostic inspection, which is extra cost. The prices quoted for the repairs have been absurd, in each case 50-100% more than available if shopping around. After having the simple things done like servicing which you are happy with and then having a paid-for diagnostic check there is a feeling of obligation to have the work done in the belief that the price is probably justified. CM clearly takes a huge chunk of money as agents.
