The Cadillac Ambulances are intentionally scarce by Mattel with only 1 to a case. But I count myself lucky to have found the only one on the pegs at my local W-Mart last nite for only $1.03 including tax!!
It does have all the markings of a rare issue, if after searching pegs & hobby shops, Flea Markets & such I can't find one, I'll pay a premium for 1.....but not a premium price for a new release, not yet anyway! lol!
