I have a 99 GTP and I get mid ot high 20's on the higway (doing around 75). In the city I get 18 or so. Before I got aftermarket rims I could get in the 30's on the highway if I took it easy

I had a 98 with CAI and a pulley. I used to get around 28-30 MPG on the highway and around 16 MPG in town.

they're good cars all around, just make sure the trans shifts nice, they are the weak link. Oh yeah I get Between 25-30 on the freeway depending on the weather, etc.
