I have seen cars that people say no, not factory paper says so. Especially if it was a proving grounds car or a GM executives car anything goes.
That scenario did cross my mind before I posted, but I thought the odds of a wagon "special" were pretty slim. Of course, what momma wants, momma gets....so I cannot dismiss that theory altogether. Although, I would have thought a GM insider would have picked a wagon that offered a little more flash than a Malibu.
It would be interesting to see if a broadcast sheet is in the car somewhere, could clear it all up.
