While the Corvette is serious competetition, there is no way the Viper is that slow. If you take the average 0-60 and 1/4 mile of 4.0 and high 11 to low 12's respectfully, the Viper wins that test.
Nonetheless, I really dont care about what the Z06 can do. My choice would still be the Viper including the additional $20,000 pricetag. No comparison.
