I don't honestly think the US has the technical ability anymore. The US doesn't really make much and hasn't since the seventies. That's a long time. How much of a Ford is actually made in the US? Shoot, how much is designed in the US?

Best they could do would be buy the parts, maybe make the frame, paint it and assemble. Don't make batteries, don't make screens, or chips, or leds or much of nothing.
