I know there's some automation involved, but overall from the looks of the doc it's mostly handmade- more so than any other american car I know of. even though I can't currently afford one I think it's accurately priced at 110k if not a bargain and anyone who's ever built a custom or pro-touring car would agree for what you're getting+a warranty.
