I own both an srt6 and an 04 commemorative edition C5 convertible (I have owned corvettes for my entire adult life. I'm 74 yrs young lol). The corvette certainly offers greater flexibility, ease of modding, lots of types of performance options, but the srt6 is as good as it gets. The C5 can't stay with the srt6, stock to stock. Remember the basic C5 is rated at 360 in it's last year (2004) and is pretty heavy compared to the srt6. I believe with non OEM tires on both, the crossfire can hold it's own. Both are fun to drive, but i really love driving the srt6 (not that the vette is shabby lol)
