Is it an Arlington Tx. Plant built car?
Would it be an SS454?
Would it by chance have a 4 speed in it?
Sounds like a Typical heavily optioned GM Zone executives courtesy Vehicle.Also known as a "Brass Hat" or "Top Hat" Vehicle.
I have some Brass Hat Car buildsheets here that reflect yours from other zones.
