Joking aside, I think we are likely seeing a 1-of-1, not so much due to AC and 4-speed, but more due to manual trans in a VIP. This was presumably ordered specifically by someone, or for someone, who had some clout to get an assembly ticket punched and passed thru.
Questions we3 must have answered:
What seats/shifter does it have? I presume VIP bench with 'naked' bench-seat floorshifter?
Otherwise, if buckets, what buckets would they be? I've never seen a buddy-seat VIP, and I presume no bucketseat upholstery was available.
Does a VIP have the sculpted rear speaker panel cover with divot in the back seat? If so, 300 or SF seats are the only available parts, and presumably SF seats would be pulled as 300 seats wouldn't be in that plant?
