Scrappies mate, place near me sells "steel" wheels for £3 each without tyres 
And to clear up confusion..
C5's that were shipped from Europe came with these wheels as transport wheels to save weight for shipping costs. Many were given hubcaps and sold on with these wheels fitted, but the early ones were found to crack around the bolt holes, hence needed the specific part number stamped into them that Scott mentioned.
Also they're almost a ceramic kind of alloy. If anyone's ever shotblasted them like I did with mine, you'll see they're actually quite porous and brittle looking.
Amazingly light though, I nearly fell over lifting them, when I sold them I carried all four wheels at the same time to the courier van.
