Hello, I'm new to this forum, my husband and I just recently purchased an 05 SRT6 Convertible and an 05 SRT6 Coupe, both limited editions. Would like to know how limited is limited and much more. I look forward to learning a lot and also adding additional features to our cars.

 

Welcome to the forum, these are great little cars, and a performance bargain.
As far as I know, there is no such thing as a limited edition SRT6. If it has a badge, maybe something a previous owner put on.
As far as numbers, according to a thread on here, there were 2944 total SRT6's for the USA, 2016 coupes, and 928 roadsters.
If you haven't done so already, you can add your VIN's to the SRT6 tracking thread, and you can find if they were previously owner by forum members.
