Im planning to get one as well. Corvette central has one for 349.00. part# 106064.
Then I saw another one at another site for 90. or 110. something cant remember exactly. They looked the same except the cheaper one didnt come up as high behind the seats as the 349 one did. hard to tell the difference in quality between the two by a pic.
TIP TO THE LADIES OR GUYS WITH LONG HAIR--If I have both windows down, with top down, my very long hair goes forward in a tornado shape into my face. (my hair is down to my belt long) NOT safe. Its important I see the roadway while driving, and for you as well. The best thing I found was to put the passenger side window up and that makes the hair flow back the way it should. It may be different in a C5, ive got a C6. If you cant afford to get one though, a wind screen, try to play with the window while your moving to see what works. No it doesnt look very good like that but at least you can enjoy yourself with top down and you wont shy away from putting it down all the time. Im now trying to shop for a throaty, growling, deep sounding exhaust at the same time. SOOO many decisions.
take care
