I was beat to the punch here, but I second the hardtop!! I have had my 96 RT/10 for ~ 6 months, and after the first couple months I installed the hardtop, just for fun...It really cuts down on the noise, and of course the sun exposure. It increases comfort significantly...I still love the open cockpit experience, but I have the option.
I would recommend figuring your wife's preferences into the equation, as the open roadster is a feel one has to like, rather than put up with!
As most folks have explained, the Viper is just something special, it gets my adrenaline going just looking at it! Let alone driving it...If it does not have the same effect on you, then the lack of creature comforts and stiff ride could easily be a problem for you...
I would go out of your way to try to drive one, even if you have to fly somewhere to do it!
