That fuel mileage is really too good to be true. I had the same car, but with the turbodiesel engine. It only got 32-33 Hwy MPG, barely beating your number. I currently have a 2001 wagon - same basic car, exact same drivetrain. It generally does 27MPG, plus or minus 1. I've seen 30 briefly - with a strong Texas tailwind during a road trip. Sedans generally get 1-2MPG better than wagons on the road due to cleaner aerodynamics.
