There is absolutely nothing. I agree that final assembly should have been made, but there is literaly not even a single nut bolt or screw attached to any peice of metal. NOTHING. Not a single weld or piece of wire.....all for $312,500.
As for $$$$$$$
A final progress payment (the one withheld) was $25k and $37k was do upon final delivery/proof of production capability. A long stretch from the $200k you claim.
