for a good one i would think around the 8k mark, you may not get service history or low miles for that money but should be rot free which is the main problem now body pannel supplies have run out. They do seem to be creaping up in price though..

check for rot around the inner wing turrets, passenger side seems to be more prone, also check for repairs here as they get plated and the problem just comes bacl twice as bad, remove the header tank if you can to get a good look. rear chassis rails are also prone as are sills etc ect.
