Tooling costs are going to be a lot more than you think. You could do a crummy sand cast for next to nothing, but this is quality die cast. An edumacted guess is $25K. If you are willing to pay $1000 a set, then figure on the vendor would buy them at $500 a set. Using the price point of the AMC centers, they probably have ~$70 in manufacturing cost.
So, at those figures, you aren't going to start making money until the 59th set sells.
So, are you going to sell 100 sets at $1000 a set within a year? People are in business to make $$...
For the people that REALLY want or need them, yes, I think selling a 100 sets in a year could happen. There are a lot of Hurst, Sport Fury GT and 300 collectors that want these as do others with very nice fuselage C Bodies.
