My 08 Sentra has a re-settable average mpg display. It was a major selling point for me before I knew about the aftermarket add ons with far more options. My firends Speed 3 also has real time MPG built in. I like the add on type setup because you don't have to spend an extra $3,000+ on a fully loaded car just to get MPG. Base models get better FE anyway.
