Does anyone know where I can down load a copy of a manuel for a 99 c5 thanks

You have mail.

Here's a link to another forum. http://corvetteactioncenter.com/forums/showthread.php?t=72324
Soft copies of owner's manuals for C5 are avail. You might have to register ( free) to get access. If so, go to C5 General Discussion area. Enzo
