Those were '05's. This was I guess an attempt at trying to increase sales of the car (not any particular model but just sales of the car itself). The rims are indeed from the SRT-6 with a different finish which IMO look far better than the all silver finish on the SRT6 rim.

Also I just noticed something. My '05 limited sits higher off the ground than the '04. I remember when i got the '05 the salesman telling me that the difference in the '05 limited to the '04 limited was no inner dimming mirror, no gloss inner finish on trim (matte instead) and the suspension was tweaked a bit for an improved ride. I didn't believe him on the suspension part but now looking carefully at both cars side by side the '04 sits lower in the front and back than my '05 by almost an inch (and NO the '04 doesn't have worn springs nor shocks). Anyone else notice this ?
