I have the 08 wrx hatchback so the 2.5 engine. Mpg is an issue for me as a do mileage for work. I get at best 27 mpg after a few little mods.
I do love the car for everything other than distance. I keep thinking about a second car for distance. But when I think about it I enjoy the Impreza to much after all life is to short to drive boring cars.
