Black wood delete Roady's don't show up for sale all that often, especially at this price. http://austin.craigslist.org/cto/2083998361.html
If the mileage is legit and it's not a rust bucket.....it wouldn't matter much what the interior looks like....that wagon should sell in minutes, not days.
I'm on the GM Longroof forum too, and a couple of guys that are on there were going to look at it at earlier today. The owner called them this morning and said not to come out, because it was sold to a fellow in Dallas. I also try to follow black WB4 cars to see were they end up when I see them pop up for sale.
