FWIW, in my only month long search for a SRT6, I've found 3 that aren't listed in the database. I was a little concerned, but realized that the database is a work in progress. I saw each car in person and the Carfax and Autocheck all confirmed they are, in fact, SRT6 models.

Do you know the total number built? Or does that increase when people find new ones?
These were all 2005 coupes, one aero blue, one gray and one sapphire.
