My Frontier is a great truck: fun to drive, comfortable, reliable, does everything I ask it to without complaining. But my only complaint is that it sucks gas like no one else's business. I average about 15-16 MPG. Granted, I live in the city, which isn't optimal for fuel efficiency, but it still hurts the pocket book. It still get's below average gas milage on the freeway (about 16-17 MPG), but it's still better than in the city. My recommendation, if you do a lot of freeway driving or don't live in the city, it's a great truck to drive. If you live in the city, you better be rich.
Lotta power, ample bed room, comfortable seats, good traction.
Gas mileage, gotta find a way to get better gas mileage!!!
