In 04 there was only 1 trim level, the only choices you had was color and if you wanted an automatic or manual. In 05 what you got as an 04 minus the auto dim rear view mirror became a limited and a base model was intoducid that came in all black, none metal door sills that didn't say Crossfire on them, no insulation blanket on the hoods underside, flat black engine cover, clothe seats and a stereo without the rear speakers and less wattage. I may have left a few things out. They also introduced a roadster and the SRT6. So in 05 you had a few more choices. Good luck in your search.
