I think everyone here gets the implication of this guy's post/thread: it's somehow weak/wrong/bad to have someone else do the work on your car. And that premise is just fucking stupid. End of dumb little story.
I'll be the first to admit that (1) I do very little work on my car and (2) I'd like to have the time to do more work on my car. However, #2 just isn't feasible the vast majority of the time. Further, I'll also admit that I think you appreciate the work more when you do it yourself. Again, though, there's the time factor for me: while I'd love to do a lot of stuff myself, I just don't have the time. That, and there are some things that, even if I had the time, I wouldn't want to do simply because I wouldn't have the experience/competence to do it. Like, I don't know, maybe installing a twin-turbo set-up on a Z06?
