Yes, in general how often should a new car like the 991 be driven.  It's my own car yes.  :)  

because i have heard that you shouldnt let it sit for too long.  or that weekend driving is not enough for these cars.  for example, my 01 boxster (before it was totaled--and even now) just seems to drive better when we drive it everyday, if it sits for a few days it shows problems.
