I agree, i started driving my red 911 a daily driver now and here in california we have a lot of Porsches and rarely someone waves back to me. So sometimes i don't even bother. I guess since they have a newer porsche than mine 77' they think they should not wave. It's really disappointing. Last night i was on the freeway, there were guys in a non Porsche that were giving me a thumbs up. So now i'm really confused.
