The 2004 models, which were only Coupes, were essentially equipped like the Limited models of 2005-2008. One just had a couple of options: stereo with or without navigation; all season or summer performance tires. Early market feedback was 2004 model was too expensive (typical of USA auto industry back then - MHO). In 2005, the Base model came out with a lower price & the Limited was akin to the 2004 model but w/o the auto-adjust rear view mirror which was discontinued. Nearly every CarFax report I've seen for a 2004 Model says the car is a Limited version. Of course the top-of-the line model in 2005 was the SRT-6. Also beginning in 2005, Coupes & Roadsters were available in all model versions. The SE (Special Edition) came out in 2006 as a Roadster in Blaze Red with a few of the Limited features on a Base model. The wheels on the SE were SRT-6 wheels with painted areas between spokes (an improvement in my opinion).
