Call SRT customer service they may be able to tell you or tell you where to call.FouHad a recent conversation with someone who had commented they hadn't seen any other Challengers on the road in my color combo of my SRT8. Of course, they had said that about my Black R/T with silver hood to fender badges, and I've seen at least 4 here in Western WA. I haven't seen an SRT8 392 on the road that looked like mine yet, so I wrote to the Dodge Customer Assistance email to ask about production numbers for the 2013 Challenger SRT8 with my color combo and option package. They indeed responded after 2 weeks. I was actually kind of shocked to see how few there were out there like mine for 2013. Here's what they had to say...
Thank you for contacting the Dodge Customer Assistance Center.
