yeah there as FP said there are a couple little things i know the main interior ones for instance on the SRT's the Lettering of SRT-6 changed from the box to the slant and the locations of that are on the seats and on the gauge and also on the car. the change was from the 05 to 06. as someone mentioned earlier the 04's came with the Auto dimming rearview mirror and that was the last year of that. and the glove compartment change was a slow hydralic that allowed the glove box to open slowly as opposed to slam down like the 04s did.
