Well the SRT's came in limited colors compared to the rest and there isn't very many made so color might be a secondary consideration if SRT is what you had you heart set on. In '04 there was no base of the base, there was only 1 trim level that was pretty much equivalent to a Limited of later years. I don't think that there was a base red one, although there was a red SE version in later years. The '04 year had self dimming rear view mirror mostly not found in later years if at all. The base cars had in quick view a black windshield surround (instead of silver) among other things. Chassie wise they were the same though.
