Average mileage for a stock 3.2 S?

It would depend on many factors. Are you doing a lot of stop and go i.e. city, or a fair amount of highway. Do yo drive it like you stole it or conservatively. I have a 2000 'S' with the 3.2 and I have never actually figured out what type of mileage it gets though it is pretty obvious when I'm on long highway trips it is pretty good mileage. On my 2007 Base with the 2.7 it shows mpg and it is pretty good back and forth to work (24 to 28mpg), highway in the 30s.
