Sounds like a nice car, but...
.. Looking at the corporate structure and other ties/companies from the key people involved, I fear that this product will be just smoke & mirrors. I maybe wrong but with 70000€/year budget you don't design anything resembling a new car. They may have some desing idea/concept or even an outer hull, but unless they got few million bucks last year and outsourced all production there just isn't any capital/personnel involved.
Sounds very much like a one mans dream (or showcase), lets see if it realizes.
