I have a 2004 that was ordered with every option except special wheels, so I have the silver painted 5 spokes. However, I was at recent rally with over 1,000 vettes (most C5s) and didn't see another set of painted 5 spoke wheels. A couple of people have asked if I have titanium wheels; lol. Virtually everyone with C5s has either has the polished 5 spokes, the chrome 5 spokes or most common of all the chrome Z06 wheels.
I have seen new chrome Z06 wheels for C5s as low as $799 outright for a set with C5 logo center caps and lug nuts and no exchange, and that's with no discounts. I guess that is why you see them everywhere.
The forged wheels that run about $5,000 a set are very rare on C5s.
The C6 wheels, included in the C6 Z06 wheels, are not attractive to me and I cannot comprehend why anyone would put C6 wheels on a C5, but some are already doing so.
Hate to say so, but with late model C5 wheels so inexpensive I would trade out teh WWs. I plan on changing out my stock 5 spokes to 3 piece forged wheels when I need new tires.
