The 2004 model is the "Coupe". It only came in one configuration.
Starting in 2005, the Crossfire Coupe came as a Base, Limited, and SRT models.
The difference between the 2004 Crossfire Coupe, and a 2005 Crossfire Limited Coupe?
The 2004 has an automatic dimming rear view mirror, and the Crossfire lettering on the hatch is in a lower position. Plus the silver trim in the interior is shiny vs the "flat" silver finish in the remaining production years.
