It is indeed at the North American International Auto Show, and I glimpsed it last Saturday.
It’s a beautiful design (the design of the headlights made the whole thing look like a Faberge egg to me 
), with an absolute behemoth of an engine and a nifty flips-up-on-both-sides hood. There will definitely be people who want to squander their money on a thing like this, and why not?
