NJS_04_996

I expect this has been covered to death over the years, but my "new" 2012 Panamera has so many bells and whistles compared to my old 911. So I'm curious to what most drivers use:
- Automatic stop/start at traffic light. Yes, good idea to save gas,, but what about wear and tear on the engine, i suspect mainly the starter. But i t does restart so effortlessly!
- Automatic air. (well, I guess my old 911 had this) Nice not having to think so much about heating/cooling....any negative effect? decreased gas mileage?
- Automatic or memory seats. Do you all turn that off and just keep the seat where it is to save on wear and tear?
Just curious...right now I'm enjoying all these neat things!
