Too bad engine doesn't run, would make for a very fun wagon! Looks like spare tire well may be rusted out from picture, leading me to assume may have rust issues underneath. Wonder what interior looks like? More pictures with ad. http://dallas.craigslist.org/dal/cto/4764345857.html
Price seems kind of optimistic given that it doesn't run and the body is in less than spectacular condition.
Very curious, this one...... The main selling feature is of course, the big block. All he says is "It will turn over but won't start." Why not? Seems to me either he knows it is broken beyond repair and isn't saying, or he's a complete idiot. Ad kinda sounds like he's young, so maybe it's the latter...... Or, it could be both. I'd start at about $1k and go from there. I thorough inspection may yield some important information.
