The Viper is pretty much still untouchable by it's closest competition - the new Z06. It will take it in the streets and on the track. When the new Z06 hit a month or so back, the forums were littered with many disappointed potential Z06 buyers, because the Z kept getting its ass handed to it by the Gen V Viper (and still does).
Gen V Vipers are a very formidable opponent...not be messed with.
So true that they did a complete butcher job and underestimated the market with the launch of the Gen V...idiots. That said, Vipers were dead in the water by the last year of the Gen IV, with 500 being made and many left unsold for the longest time, including the so-called "limited editions".
I still love my Gen IV roadster, despite it missing any and all creature comforts, and being a seriously uncomfortable piece of shit to drive - LOL
