Good question but hard to answer.
Obviously the perceived value is in aluminum. The price to get aluminum has not only come down since the inception of Kirkham but, became more readily available. To get the likes of McClusky or the other big 3 US based aluminum guys to do a car by hand definitely took some time..
It's sometimes odd to me when such odd things sell and some not so odd things don't sell.
One of the 1st glass cars sold at barrett jackson at $115,000 a few years ago then a friend of mine sold his glass car for $112,500. I thought those numbers were the world then I sold mine for $125,000. Go figure. Mine was the only one set up like a comp car and was truely a track car, The guy that bought it made it a really nice street car and thoroughly de-comped it. He thought he would like it that way but, that is not for everybody but it brought the excitement to the sale.
Then we have the Shelby Supercharged cas that looks likea modernized comp car but sounded like a grocery getter. That webt for $200,000 in glass.,
Getting back to the issue, In Shelby Only, I see a 15-20k spread. The kirkhams are going for less,
People want,,,,,
1 - SHELBY
2 - ALUMINUM
3 - Detail & Correctness
4 - as per 3000
Anything else better be cheaper, I think glass will fade out unless it is greatly reduced in price
