Thoughts of this dealers policy on possible purchase.

Dealer claims that the unit was special ordered with full body paint, unlike most of that year/model. Proof of that? Perhaps the previous owner just recently decided to add full body paint to a very weathered exterior, perhaps in Mexico (would explain the immaculate appearance for an old coach just as easily as "taken care of extremely well".

BTW, Carfax, even for cars, isn't worth the paper it's printed on.
