If collecting, yes.
If driving, no.
From a price|performance standpoint, it gets no better than the Viper.
Actually, that's probably not true. A Mustang probably has the best price|performance ratio.
But when you factor EVERYTHING in (performance, looks, exclusivity, fun, fahrvergnügen) the Viper has the best experience|price ratio. Who else offers a $100K car that can beat cars 2x - 5x as expensive?
For a supercar you can drive everyday, nothing beats the Viper.
