The cruise nite is in Richmond,Illinois. Right on the border of Illinois and Wisconsin. I believe this car is a clone . They didn't make many GS 's so i would imagine if you owned it you would trailer it. It was corvette nite last friday so if the owner shows up again I will try to get more info.
I think it`s a pretty safe bet it is a clone (although a nice one)...a real GS is worth $4M as in MILLION, there were and are only 5 built.....is there a cruise night every Friday in Richmond??
