Strange thoughts come to my mind from your predicament.
I wonder if all those who have thought technicians cost too much see anything wrong when one is lost to driving a Bus. You are obviously an Allstar. It should be that you would have an easy life doing what you like. MB repair at your level should return to you that which you have obviously paid out.
Good Luck with whatever you like.
