"Ten (10) Grand Prizes: Winners' choice of only one Chevrolet, Buick, GMC or Cadillac vehicle, the estimated VRV of each prize vehicle not to exceed $131,681USD/$130,937CAD"

That basically states that the ZR-1 is available. So yes, no matter what GM car you want, get the ZR-1, then sell it and buy that GM car yourself for $$$ profit. Also, the $25,000 they give you to offset taxes - don't you have to pay taxes on that as well? Obviously less of a tax burden than $130k, but still. I seem to remember Oprah running into this problem with all those cars she gave away.
