I don't know John but I was having conversation at SEMA with a real nice fella from Texas who was explaining some car building his son-in-law (or son) was doing. Turns out it was John.
For anybody not in the know, he screwed countless Viper owners by taking their cars (to twin turbo, or similar), then parted them out and did dick all to the cars. Cars he did end up building used to blow up regularly.
Don't care how many fast cars he built, he's a crook, through and through. Probably still has all sorts of pending litigation.
