Seems high to me, but I'm a cheap bastard when it comes to buying cars. I would think the significant rust thing makes it a non starter at that price, but you can always come down. The thing about cars like this is the excitement buyers get when they are standing in front of it, the money burns a hole in their pocket. The trick is to get them to the car. $6000 and "significant rust" and the lack of pictures of said rust is a bad combo, people won't come to see it. Also, get rid of the 200, 300K + mile line, that will scare off most folks, save that for the face to face conversation.
