I see more 986's around here than I expected. There is always a head nod or a wave. I've also exchanged greetings with Caymans and old 944's. I've even exchanged a lot of greetings with people in other brands of convertible (we got a buttload of snow this past winter, so we're probably all just excited to be driving around with the top down).
As others have experienced, absolutely no love from the 911 crowd
