2006 Mazda MAZDA3 s Grand Touring 4dr Hatchback (2.3L 4cyl 5M)
I bought my 06 GT 5-door to replace my 04 3 sedan, which I loved aside from the cargo carrying limitations. I have 3 dogs, and occasionally have to transport them 150 miles to visit my mom. I also went for the GT hatch because of the new features (for me anyway) such as leather (heated) seats, auto climate control, information center, auto lights/wipers, and 5 speed auto.
Interior design and comfort befitting a higher class of car, 5 speed auto (lower rpm cruising), cargo management system where the panels can be arranged in multiple ways, auto climate control, and A/C seems better than my 04.
Not much....the BOSE stereo really doesn't sound all that much better than my former 04's stock system.
