Ya but if you give in too often your car will end up looking like either of mine
I saw someone in a blue RS 2.5 yesterday with SCCA stickers.. i wanted to chase him down and try bidding on his Oxygen sensor harness, but i was in route to pick up stuff from UPS.
I've noticed that less people wave back in Reno, than in Tahoe (where there are PLENTY of Subarus), i only ever wave or peace sign turboed imprezas, I also do it from my rally car but i get a much lower return rate there...
