Depends on who you ask, I suppose. Let's put it this way, IMO, he's always been rather cagey on how he obtained some of the parts he sells. I've gotten different stories from him about what was refurbished and what he considers "NOS" and "new". Blurred lines with different accounts of his products, it seems. Oh, and Lord help you if you ask questions about his stuff he's selling.
He also acts like a sniveling little child sometimes and refuses to sell you parts based on bad information that's in his head. Then throws out incorrect accusations of how you screwed him over on buying a part, and it was over a part that someone else must have purchased. Somehow he he felt he got screwed on some inner door panel arm rest pads. I know for a fact I purchased all the ones I have from the GM dealership and never purchased any from him. According to the accusation, I "screwed him" by purchasing them from him, then selling them to someone else for a profit. How he would even know my personal business dealings with someone else when I don't publicly share that info anyway is anyone's guess. Even if it were true, which it isn't, what gives him the right to approve or disapprove what I do with my own junk after he got paid? And obviously he had no record of it for proof. Maybe he's gotten some help over the years and that ain't the case any longer. I just don't know. I've never sold any new armrests to anyone to my knowledge.
So, yeah. I got reason to question his legitimacy.
