As far as price you would need to speak to Joe at Panel Craft. As far as rolled versus stamped I would suggest that in the end there very similar however handmade will always have a place with those that see the value. Why does Kemper, Howard, McCluskey, and Panel Craft restore originals and continue to survive, I would suggest for the value as it was made by an artisan.
I can buy a stamped out pair of Hush Puppies dress shoes but a pair of Bontoni leather shoes are simply better and yes cost a bit more. Similar analogy, why does a Contemporary Classic have less value than KMS? It is the cost of the art..... Same analogy can be drawn. I can also buy a Picasso print for $25 however the original made by hand holds a bit more provenance and value.
In the end I think Panel Craft, Brooklands and those that do it by hand will always have a place in this craft. If you want a bargain call FFR as their business model is a $50k car for $15k thus everyone has their place. It’s a matter of preference and desire for something special. This is the reason I had hood, boot and doors made from aluminum versus using my glass skins, something special....
This car completed by master builder McCluskey, Howard, Acton, Kemper would simply be a work of art that could be driven either on a track, show stage or if you like sitting in your garage just can't get it for the cost of a glass kit car.
Whether it be Cobras or anything else in life you get what you pay for.
