Yes, just push the button now...
I wish running a CNC were that easy!
As for slipping a "new chassis" under one of our earlier cars--not going to happen. Way too much work. It would be easier to just start over fresh and new. You are right on the Lego set thing. We did it that way on purpose. We were very careful when we made it so that it would be easy to put together. We spent a LOT of time programming the machines to do all of the hard work. When the parts come out, we pretty much just bolt it together.
If the customer doesn't care, then I think we may start making a few more of these. We won't know until delivery, however, what he wants to do. Of course, that depends on whether or not customers want a billet chassis instead of the original 4 inch chassis. Maybe I should post a poll???
