There were only 5 exterior colors for the 2004 Crossfire:

Black
Sapphire Silver Blue Metallic
Inferno Red Crystal Pearl/Blaze Red Crystal Pearl
Graphite Metallic
Alabaster

PS3 or 368 are the color codes for the SSB. If your Crossfire has its original paint job and appears to be a light silvery blue in color it is definitely SSB, PS3/368. The graphite metallic would be the only thing remotely close for 2004, and it doesn't look blue. The problem is that the paint codes are not easily found on the Crossfire and do not reside in either the common Chrysler or Mercedes paint code locations. One forum member reported that the paint code was found under the rear bumper cover.
