I'm putting on the Nomex as I write this....
If you like driving fast and nimble cars, you'll love the Viper and can get used to the visibilty issues fairly quickly. IMO, you will likely never stretch out and be totally at ease driving this car in most every day situations. It is just too quick in all respects to let your attention wander at any time. Vipers are regularly compared to Corvettes. Corvettes are great touring cars, especially for long distances...Vipers can wear you out on some of these types of trips...if it wasn't for the continual fun and thrills, let alone the attention the car brings. Yup, visability isn't as good as my wife's Mercedes, but it's better than the 1993 Honda Prelude she had lots of years ago. But the Viper (and I've owned both the R/T and the GTS), is a handfull and it's the most fun you'll ever have sitting down.
