I've gotten the "that's not a real Porsche" comment behind my back, but the originator likely didn't even own a car.
Did get a "gay car" comment once on the way back from a range trip when I let my friend drive it. His witty retort was one for the record books.
One time I had the 964 out recently I waved to a Boxster driver, and he waved back enthusiastically, sort of in a "Holy crap a 911 owner acknowledged me!" sort of way.
