Building a mass-market consumer automobile is an enormous challenge with massive startup costs, endless regulatory challenges and ruthless profit margins. By contrast, supercars are pretty easy, but that's not to say that every small-scale startup works out.
The car business is littered with failed supercar startup companies, and for every Pagani there are a hundred failures like Vector.
Vector Aeromotive was supposed to build a world-beating hypercar back in the cocaine-binge ‘80s, but it didn't really work out. They started off with the W2, then 17 of the pictured twin-turbo W8s, before they finally devolved into building re-bodied Lamborghini Diablos and assorted vaporware that still pops up now and again.
What do you think was the most outlandish supercar that never was?
