I believe I stumbled upon a '68 or '69 Belvedere...

I can get it for 200...
Maybe i'm being a little naive, but I have been looking on ebay at things this car would need...OEM/used stuff, and the prices are no different than parts for my '65 Biscayne or my '70 Chevelle (Chevelle stuff pricier than the Biscayne stuff tho...).
