A hard fast answer you will not get on model cars being tooled now. The model companies are all very small companies and this kind of info is not usually public. It's a lot!! But the total cost of research, planning, drawings in 2-D and then 3-D, tooling samples and then molds. But it doesn't end there. Moebius had to almost scrap the original Hudson mold as the green house was wrong....the bad one wasn't free! So the total cost will be a combination of all that. More than you think...let's leave it as that.
