Yes, it has been over a year now.
I still have both the C5 and the Viper.
The comparison is not typical because the C5 has 2 turbos.
Attention: Viper wins hands down. Absolutely no contest.
Feel: Viper wins. The steering has better feedback.
Comfort: C5. Easier to get in & out of. More room. Real A/C.
Speed: Not a fair comparison.
Quality: C5. My Viper has many tiny issues.
Not that the C5 is all that great in quality.
Now, just wait until I get 2 turbos on the Viper.
