I agree on the used parts issue. I don't deal in used parts because of the issue that they may not be operable and there is no warranty on any used part. Even still, if the part fails a few months down the road the customer insists that you warranty it. I have run into that in the past where will get a used part and it is broken in some way or it is not functional. We also have gotten out of the habit of allowing customers to bring in their own supplied parts whether they are new or not. You lose on the profit margin and you can not operate or survive on labor time alone. Alfredauto brings up a valid point about someone not being able to afford the work being done. Although I feel for them, we have to make a living too. As much as you would like to help someone out and keep their expenses as low as possible, I have found that it will come back around to bite you if you chose to go the used part direction. As much as I hate to say no to someone or turn them away, I have just gotten in the habit of telling people that is not the way we do repairs. It is either the right way or no way. We do not like to cobble things either. It is a hard pill to swallow but you have to look out for yourself and the success of your business first.
