Alu and carbon fibre body. That'll cost silly money.
They also don't need 1000's or even dozens of people to like it. They just need 12 people to like it. So pretty sure they'll sell them.
The link/ article is 18 months old. I wonder if they have sold them all? I suppose there are bound to be 12 idiots with more money than sense in the world at any one time.
I just don't get where these people (it's quite a common thing to spend loads to build a 'limited run' kit car and try to sell them for £100k plus) get their financing. I don't think Barclays or Santander would be interested, unless you had a VERY persuasive business plan. Maybe they all have rich parents?
Although I do remember my accountant saying to me once that it was easier to borrow £10,000,000 than £10,000. I never tried, although I did think about it once.
