This was attempted a few years ago with the XA-XB-XC Coupes, heaps of 'interest' and 'yeah lets go for it' from loads of people....
A coupe was located and offered to the builder (Dynacorn) for 'copying', when the costing came back the majority of the interested parties evaporated overnight....I can't remember the exact details but Dynacorn needed to cover the tooling by taking guaranteed orders (deposits) for something like 150 to 200 units, i think it was about $30k+ per unit less freight, and that was before you got into the ADR side of things.....so yeah, the interested
Unlike the US (UK/EU) we don't have no where near the numbers for exercises such as this to make it cost effective, and did someone mention ADR......
