I have seen several in and around Rhode Island. Two red ones I see a lot of, a grey one in warwick that's listed for sale, 4 White like mine and a couple of yellow roadsters as well as Pete's gun metal roadster.
I've had several people tell me that there is a lavender one around. I know Chryler didn't do that, it has to be a repaint. Odd color choice but the people that spotted it said it was nice.
Personally it sounds like brokeback Crossfire mountain to me..... I did see a few SRT's besides the two I went to Newport with. A black one that was being fitted with a boom box system in the deck, a saphire blue that is owned by a dentist who doesn't want to be bothered with any club stff, snotty race car driver type, Two silver coupes and 3 Black roadsters, a black coupe and the first roadster I had ever seen, a base model with SRT wheels in red.
