I can apprciate how completion times could put him in the trick bag........and for him, he probably doesn't need them. More than likely, he has more paying customers than he can do a quality job for. With GYC.....cars in his shop do not seem to stand still just collecting dust taking up space.
My wife learned the lesson regarding completion times a few house builds ago..... She (and everyone else) would ask (even at the start) when it will be done? My standard answer is ....2 weeks (the carrot). It took her a while, but she finally got the message. All that matters is that I am working on it and moving forward. My preference is it be done right....not right now.
