Only taking into the account of the numbers game, and leaving emotions aside, whoever bought them at 122 got a pretty decent deal. I'm guessing, and I could be wrong, that the owner lost out money on this deal. Just a guess. Have no idea.
Considering the inflation priced into the equation, each of those cars sold for a 1987 equivalent of around $27,500. Considering they were what, 18K list price? That's 9,500 more in 87 dollars, or in today's dollars, $21,000 adjusted for inflation.
Thusly, IMHO, the 122,000 for so-called collectability isn't a horrible deal as far as strict numbers go.
I understand they're not technically new new, but even the mighty Grand Nationals aren't proving to be an extreme high value car in the collectible side of things. I would consider these some of the most rare GN's in general.
Would I own them? Not sure. I still have a hard time trying to consider buying any G-body that's not an Olds. I did buy a new '86 Monte SS for my (ex) back then, but that's because it was what she said she really wanted.
But when cleaned up, the twinz sure are purdy.
I'm sure they're going to live a pampered life.
