I don't have one, but my brother bought an 05 Copperhead edition last fall. It was extremely clean and only about 16k or so miles on the clock. Had a cam change and exhaust - supposedly dyno'd at about 600 HP or so. I've driven it once and it was a lot more fun than my 73 Challenger which brought about the same money when I sold it last fall. The viper gets a lot more looks and also had air conditioning. I'd definitely consider one the next time I am spending fun money!
