I'll vouch for Ivory's writeup.
The places on the strip are beat cars. I flew down and took a GTS out for the day before I bought mine as was almost turned off the car to the point of not buying one. That was from exotic car rentals. The air did not work, steering was baffed, brakes were toast amongst other things.
Even if the cash is a little higher go with rent-a-vette, I did my research after the fact on rentals.
Good luck and have fun!
