I really struggle to have any confidence in things like the Spania... new manufacturer turns up with silly headline power claims, mega list price, and expects the super rich to jump on the bandwagon.
There are maybe 2 companies that have done something like this to a decent level of success - Pagani and Koenisegg, with Pagani arguably the most successful.
Pagani started by getting the basics right - engineering, build quality, handling - and built a following off this. The mega power stuff came much later in the development of the cars/brand.
I've no idea how anyone would have enough confidence in something like this to part with their money!
