Fred, I think this thread is a testament to your good nature as a friend and businessman. It's a shame that the customer/friend keeps bringing the car back, but maybe these could be teaching moments for him. Instead of doing all the work, make it educational and get him to understand the work that goes into fixing his, err... umm, "tinkering". Hell, maybe he will even appreciate the understanding how things work and a little more confident in ownership.

Saying "I fixed XYZ" sure feels a lot better than "my mechanic fixed XYZ".
