I live in the northern suburbs of Indianapolis & have been to J & S to look at cars, but never bought from them. Generally what you see is what you get. I do not know anyone who has bought from them, but the rumors around the Vette people in the city are to really look over the car carefully before you buy. When I was looking for my first Corvette, I went up there & the guy who runs the place seemed to care less if I wanted a car or not.
If you would like, I may be able to look a car over for you, it is about an hour and a half a way from my house. PM me if I can be of any help.
