I think there are two types of prospective Viper buyers. Those that want one because of what it is, not so much because of how it drives. Magazine/forum reviews and owner feedback confirms all they need to know, and they don't have to drive it themselves. They already know about all of its strengths and short-comings, and unless they have some sort of physical issue they don't need to even sit in it. Many of the multi-Viper owners here fit that profile, having ordered theirs pre-production without much info. They are diehard Viper fans, and if they like the car going upscale they'll want the Gen V. Buying a Gen V is easy for this group, with delivery time being the hardest part.
Then there are others, like myself, who have driven other makes of sports cars and are more interested in the details to decide what they want to buy. They aren't commited to Dodge, SRT or Viper in any way, and may even be sceptacle of Dodge quality, with any previous cars in this price range having been high-end import brands. Had the Gen V not moved upscale it wouldn't be on their radar at all. Brand image may be as important as the car itself, and the ease or difficulty of the dealer experience will be key. The latter is obviously shaping up to be a problem for some, and a complete deterent for many I suspect. And some of these will sit on the sideline for a while to see of the situation improves.
