The 2005 Mustang interior looks waaaaaaaaaaaaaaaaaaay better and much nicer than the Mazda6 interior.
I don't like the Mazda6, but I like the quality materials that they build Mazdas with. I know someone who owns a 95 Mazda Protoge. It's got over trouble-free 200,000 miles on it and it's still on the road without any problems. The new 2005 Mustang will be better built like the Mazda vehicles when they start building it at the Flat Rock plant.
