im not the definitive source on this but when i talked with him awhile back on a car i was looking at he asked me what info i had. i told him about the car what i knew. he said get the vin and tag info. do research of your own. such as title search, get any documents of the car that you can.he will ask questions about things he did to the car to see if they are still there. hes a man of his word. he wont piddle around he will tell you whether its real or bogus and if someone steps on his toes (selling repop parts, selling clones as originals or making up or falsifying documents) he has no problem introducing the perp to his attorney. he a great guy. the few times i talked to him he was blunt and to the point. if he says hes got the proof if the cars a real deal or not you can bet your rear he is telling the truth. he does have the documents. 2500 is his price reguardless of the outcome.
