I'm getting 15-ish MPG, but that's a bit different. Stock-ish (headers, tune, pulley, etc) will get 25+ with a light foot. No awd ones from the factory unfortunately.
What about an Evo IX or X?
Eagle Talon. Can be "quick" cars for cheap. Or AWD Blazer and put a turbo'd junkyard 5.3 in it.
WRX's seem so raceboy to me... Nice cars though
Edit: didn't see the "fuel efficient" part. Forget the turbo 5.3...
