Mostly the new ones drive around in my town (not in my street though)... no Do It Yourself-ers... all maintained by an Official Porsche dealer.
There are a few air-cooled models still around, but don't see them out as much as the 996 and 997's.
But the immediate neighbours: one's got an Audi TT and checks out my 911 everytime I drive off (or overtake him
).
