Wayne, what is it exactly that you are trying to do? If it is to build a buck, you can spend a great deal of time and money and trial and error to do that, then spend a great deal of time and money and trial and error to build the molds, then spend a great deal of time and money and trial and error to build a body, and you can reinvent the wheel that way. If it is to have molds like you say in #8, if I understand correctly Inspire has sold his molds but he had to have had a buck to build them in the first place which he may still have. If so, he could make another mold then you could make your body. I do not know how many cars you intend to build, but amortizing the cost of that mold for only one body makes this route cost at least twice as much as it should. If it is your intention to have a Aventador body, cut out all of the other steps and duplicated expenses and just go get one from duraflex-racing.com. The fringe benefit of this way, and this is another huge cost consideration, is that unlike all of the other options a readily available $200 windshield works with it.
