Not sure whether the legal department from the Porsche folks here in Stuttgart would handle the IPR-issues the same way Ferrari does.

But there is one thing for sure: They (quite rightly) wouldn`t put up with everything.
Fran and all the other manufacturers would never dare to sell a finished car with a Porsche badge on its nose, not even upon customer´s request. And why should they if it´s then each customer´s own decision to do so.

I was once given access to the Porsche archieves. Press articles, manuals and stuff like that can be researched quite easily. But all the original blueprints and parts lists are locked away behind steel doors.
