Yes it does come in handy, work that I can't do, don't have the tools or want to take the time to do he does for me at the dealership. They let him work on personal cars when he is off the clock so he works on my car at night. I drop off my car after work, drive his car home and he drives mine home when he's done. He does charge me but only $25 and hour and he does upgrades to the computer and such for no charge.
You see what you want to see and you hear what you want to hear.........
