Maher ZL1 in Corvette Fever: Question

[TimG]

I remember the white ZL1 press car with the automatic transmission locked in Drive (to avoid blowing the engine) being a 1968 fitted with a ZL1 engine. It was a white roadster with a hard top and dark stripe the length of the car. The door push knobs are a give away to the year.
I understand that this orange ZL1 was discussed at the NCRS Florida meet and the tank sticker was felt to be authentic. The feeling is that there were more than two factory ZL1 Corvettes built.
I visited with the owner of the orange car at the Fall Vettefest in 2004, very genuine and pleasant fellow that enjoyed talking about his car.
