http://www.autotraderclassics.com/find/vehicle/vehicleDetail.xhtml?adId=473266&conversationId=6437 Here's a 65 GS for not much money... If you are on the left coast.
It was here http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=220797261389&ssPageName=STRK:MEDWX:IT last week, sold (supposedly) for $1825.
Wow! $1825 was a great deal. I guess the new owner is trying to make a few bucks. Too bad a real Buick person didn't get it. Looks like a good car to restore. Not many 65 Gran Sports out there...
