I don't think they look too realistic but still. Pretty interesting. This interior looks great. But again, I'm not sure how close it is to the real thing. The exterior seems to have too much details for a Porsche. So who knows.
One thing is sure, Porsche will not disappoint with their new sedan. It should be pretty amazing. For those who can afford it. I guess 4 doors will be pretty unique in the "around $100 000" sports car market. (The Aston Martin sedan will be much more)
