Look, I don't like any tech, no matter what the age, that does not do as promised and LIKELY misrepresented himself and capabilities but this piling on is only based off of what the OP has said and while I believe him in every way, too many are piling on without both sides of the story. The fact that the rig was left for a year, to me speaks volumes about poor decisions from the rig owners side. Are you seriously trying to tell me that a 70 year old man was that sly to be able to keep a rig for a year just by making promises after promises. I am sorry if the OP gets mad at me but I just don't think the whole story is here and not because of the OP but because of his slanted side of what he knows. The mileage part of this is disturbing to say the least but ONE WHOLE ******* YEAR AT THE SHOP! Come on man! Hell, before you know it, this old guy is gonna be on death row. I like to make informed decisions and that means knowing ALL the facts. The one year time frame is glaring to me. Hell, this reminds me of an impeachment process I know a little bit about.
