No it's called reality, welcome. Every RUF starts as a Porsche built body and chassis that isn't marked so it isn't beyond any stretch of the imagination to call it a Porsche.
You certainly have some issues man. I do not discuss what is "common conception" or "common perspective" or whatever. When you bring in discussion, than do not discuss in approximations or conceptions but in finites and facts.
RUF is RUF, Porsche is Porsche. When you register your RUF it says RUF on the licence.
Same as for BRABUS.
Of course everyone knows what are the *bases* for building them, but authorities and companies have basis to claim the originality of the brand and it is both officially recognised and officially registered as standalone manufacturer with appropriate status.
RUF is RUF, Porsche is Porsche.
I really can't understand why are you so stubborn.
I hate to break your feelings but the developer is wrong, that car is indeed a RUF.
What feelings? What is this above? Oh, I see. You probably missed my own post above. Whatever. You are really a strange person.
