Have a 2005 xB and i'm a easy driver. Get around 33 MPG city/highway mix. It doesn't have alot of Horsepower but it gets me from point a to point xB ;-)
Great thing I love about this car is the Room! I can put soo much in the car like an SUV but not pay at the pump like an SUV.
Another thing is the seating, where it's high but not too high where you've got to climb into a cockpit like a SUV or truck.
Wish I could get better MPG then 33 lol. But one thing would be Horsepower, but not decrease MPG due to that. Another would be a telescope for the steering, and a upgraded stereo systems to play really loud.
