87CandyBlueT seeing as your from ky, i would suggest getting a new radar.I personally run the Escort 8500 x-50, and i run i-64 just about daily, poor state boys and sheriffs have a hard time competing , esepcially over the long hills and through the long turns.
To speak on how fast some of the cop cars are. I once passed a state cop goin the opposite direction. I was traveling 85 or so ish, i knew when i passed he was gonna turn around, because the sillyness the cars in front were doing.
All i know is this guy had to be flying to u-turn and catch up to traffic in less than 30 seconds.
I havent seen the corvette cops but i have seen the camero's and some of them seem modded, i would say u need some shit under the hood to get away from them.
