From my memory, a lot of the excitement was directed at what the design was trying to achieve: a structural body made from easy to make pressed steel panels. This was meant to enable a much cheaper car while also removing the bottlenecks plagueing Tesla's production lines at the time

None of this materialized. The truck that ended up in production was a traditional body construction, but with unpainted steel panels so it looks like the truck Musk presented. It ended up with all the drawbacks of a steel body, while still being expensive and hard to manufacture
