A great read on Model 3 manufacturing costs:https://www.bloomberg.com/news/features/2018-10-17/tearing-apart-teslas-to-find-elon-musk-s-best-and-worst-decisions?srnd=hyperdrive
“Sandy Munro, the founder of Munro & Associates, a small firm that disassembles new cars piece by piece, concluded that the Model 3 costs about $2,000 more to produce than a similarly-priced BMW i3 and may have additional cost problems in its assembly plant. Some compact cars and family sedans produced by conventional automakers don’t make $2,000 in total profit per vehicle.
Many of the problems stem from unconventional choices made by Tesla Chief Executive Officer Elon Musk. “If that car was made anywhere else, and Elon wasn’t part of the manufacturing process, they would make a lot of money,” Munro said in an interview. “They’re just learning all the old mistakes everyone else made years ago.” Munro said he admires Tesla’s technology, so he sent the company a pro bono list of 227 suggested improvements.”
