I do not have any direct experience with Porsche but I do have a lot of experience with Apple, another firm known for its excellence in design.

And if you want a long term legal battle, then go ahead and create a new design that is somewhat reminiscent of their design and call it your own. Apple will quickly issue legal threats, get court injunctions, and have your products impounded by US Customs until you either run out of money or just give up.

Ask me how I know.
