I think that you guys could be sitting on a gold mine in a few years. Looks like the SRT is a very rare find indeed. I wonder why they are not producing them this year.
I can only imagine the power of the SRT. I own a Dodge Durango with the HEMI which only produces 335 hp. The SRT produces 330 hp. There is no comparison to the power vs weight ratio. My Durango will get up and go but I don't think it will compete with the SRT other than I've got a little more room inside.
I can't wait to get my hands on a SRT.
Did they only make them in 2004 and 2005? What is the most popular color? I would bet it's black.

 

They were made for model year 2005. However, 3 2006 SRT6s have surfaced and been bought by forum members.

Made in 4 colors.
From most to least produced:
Black
Aero Blue
Gray
Sapphire Silver Blue

Per Chrysler's only released production figures: 2,016 SRT6 coupes and 928 SRT6 roadsters produced - that's it.

Good luck.
