I have made a significant effort to disclose everything in the craigslist add. As with all these rigs there will always be something to maintain, improve or modify. I already have plans for my Traverse. When I hired out to have the GT buffed out I stayed inside while they hit it with the pressure washer to check for leaks. As suspected a little moisture came in from the rear window. But if you look at the trim you can tell it needs to be replaced. There was no evidence of any other moisture intrusion other than some misting from the tail light area. For good measure I would reseal the two side windows while I was at it and replace the foam weather stripping around the side entry door. Typical for a 87 GT. The seals on the front doors and front window are good. Factory rear tail light replacement parts are not available. Some have replaced them with after market units. Personally I would clean up the existing ones seal them with either a rubber gasket or possibly a marine caulking. These items will take a few hours to do but at very little cost. It came with a donut type spare that is the original and I would never trust it. You could mount a full size spare on the existing back bumper mount. Also since there is no black water tank the stock spare tire mount underneath is also an option. This last weekend I tried the cruise control and it was not functioning. It appears that all the parts are intact, I have not investigated any further.
As far as the top, it has dimples from being in a hail store. lots of hail in Texas which was its home most of its life. The curtains where falling apart some I took them out, but have them in case a pattern is needed and all the attaching hardware is still there.
I have had several inquires on price movement. I have a bottom line and have no problem moving to that if it doesn't move in the spring. I only know of six other actual 4x4 GT conversions. One sold for 28K last year, yes I know thats a lot of cash. And there is some flexibility before testing the spring market. One also sold for 11K last year, I know the owner its needs all of work. Another sold for 18K. I am an honest older adult seller and will give you the grand tour if you decide to come see it.
I have had several low ball 12 and 13K offers from people fishing without seeing it. I will not be selling at that price.
