Seems like since I have a little more time to work on my own car, all my friends and relatives daily drivers take a dump and I've spent the last 5 weekends under somebody elses' car and not my own. How often do you get dragged into doing things just to save them a little $$$ and get them back on the road quicker? When do you say enough's enough and tell them to "take it to a mechanic"? I don't want this thread to turn into "this one time" stories, but I'm asking for advice as to how to tell them that our free time is valuable to us. Thanks in advance.
