When I started my 911 search I was shopping for a daily driver with A/C and the creature comforts of power windows, mirrors, etc. My budget dictated that I stay in the SC model years. I'll never give up my '81 but someday I'll build a nice '73 RS clone for weekend trips to the grocery store.
Actually, I'm hot for a 911R clone right now. There's even a '66 for sale near me...
