reworking a fully restored car

You know, it's not called slander if it's true.
It's called a rip off and you could very well be the one that puts him under.

The "we'll use our trust to sue" threat is empty, and so will the trust be if they try it since you have proof of the work done.

I am fully aware of Canadian law on this matter , this is why I am creating a photo record of the fraudulent work I was charged for , I may not have a printed receipt but I do have bank records showing a pattern of withdrawing large amounts during the time the work was performed , as for outing him I already called him a Scammer and a Thief openly by name on the Canadian Mopar forum and have tirelessly shown his work and warned everyone who would listen, I have already cost him many times the amount he scammed from me . He isn't going away because some people just think he will treat them different and in the end they end up scratching their head wondering why they didn't listen, sore assed but too proud to stand up and admit he did them too .
