We know some of that. The first 23 (of which the number could obviously be changed - it isn't like RedDot needs to keep their model when they are done with it) are being built by hand in Michigan. We know they've made steel body panels already and are "soft tooled" in that aspect.
How long does it typically take to produce hard tooling?
We can get hard tooling completed within 16 weeks after receipt of order.
This is from http://www.advantagefabricatedmetals.com/metalstampingfaqs.html#q10
Even if the panels are stamped, it isn't necessary that Elio actually do the stamping. They could buy the body panels already stamped out. I know GM bought the Isuzu Hombre hoods from somewhere - Brazil, I believe. It's possible to outsource the stamping but not optimal. It's also possible they could outsource the engine if they needed. Elio shouldn't have to do any "stamping simulations". They've already had body panels stamped using the soft tooling so simulating something that was already done would be kind of silly.
We ALSO know they will build the 100 (if that order is still valid) at Shreveport.
You said "We ALSO know they will build the 100 (if that order is still valid) at Shreveport."
I have always questioned the claim of making 100 for fleet customers. EM came up with that when they could not meet production deadline for reservationist. It created the appearance they would be making vehicles by the production deadline, but explained why no reservationists will be receiving a vehicle.
