The thing I don't get is why wasn't some of this stuff inspected prior to the final sale? Or before selling the motor in the first place? Mark should have known better to inspect the motor before buying it, but you should have also known what you are actually selling before you took the money and "hoped" it would be ok.
Oh yeah and Mark is good friends with the owners and admin of this board so you are going to get flamed and shit on no matter what you do, so good luck with your rant.
