Alright, some bench racing!
From a quick look on the internerd:
The SRT8 creaked our scales at 4,234 pounds
Quarter mile time is 13.6 seconds at 105.8 mph
For the C5:
Weighs in at 3250lb
records a 4.8-second clocking to 60 mph
For a 2001, Quatermile time is 13.1 at 109mph
Does not appear faster to me.
So, it appears as though it is probably more down to the driver than the car and even if it is not quicker, it still has one heck of a cool factor to it and would not deter me from wanting one, or getting a ride in one some day.
Oh yah, you are definitely welcome to bring it out! I would love to see it....although this weather may not allow an outside meeting this week.
