Those factory wheels are sharp. The recent Bonnevilles 00+ look great in play. (Saw them on the "Official BC Wheel thread", a couple of the members have them on pre-'00. They go about $800 used, on ebay. :( For that you can get a big choice of aftermarkets.
Not to jack the thread, and supply some unhelpful info.....
If you like the curved supports, these are the (opinion) best I have ever seen.
A while back, I cropped them out of a BC members pic. They were a little over the $200/per price when I searched for them at the time. Of course now I can't remember who had them, or their model. And a quick search at retail sites, still no luck. ( i know, big help)
The point is... $775 may not be completely out of line for the market, but that price leaves a lot of aftemarket alternatives.
