Here's my opinion:
There are no rights to buy !!! As things are, Gerd hasn't patented anything and the Durango is only a concept, but NOTHING prevents anyone from using that same concept. So Gerd has nothing to sell apart from the drawings for his car, but anyone could copy the whole car while slightly changing every part so that it doesn't fall into the realm of copyright. Which is what, as I understand, Aero did.
However in such cases, a gentleman agreement would have been a minimum. One side states it has been done, the other states that it hasn't been done.
To be frankly honest, I don't really care who's right, but as a design engineer I'd be quite upset if someone had blatantly copied me and then pretended I'd agreed with it.
