drivers of older vee dubs do don't they do that hippy peace sign?? haha
i think most people do if they own something that's older, unique, unusual or just not many around... yes I know there's quite a few lines around these days but they are still kinda special and people who own them are enthusiasts.
Damo will give/get waves from people in other GT's, even though it's a new car, just because there's not that many around, and people who drive them will always notice another one.
I don't think you'd get that with BMW drivers and lots of other newer cars.
