~$250-400k but there is variation based on size and other options.
Based on their comments on the podcast, there's not a production line per se but instead an apportionment of space on the shop floor. I think that based on the size and amount of time to build, they're not moving them down the line like one would see at a car factory.
As another posted said, many posts on here have tracked down customers. There are numerous posts from the company and their customers on social media, and I find them to be credible. In particular, the user fab_motors on instagram appears to be a contract welder for them and he has posted a lot of in-progress pics.
There are legitimate concerns to have about this company, but I think that even the most critical (of BBRW) posters here would acknowledge that this is a real business manufacturing a real product.
