I found a 17,000 mile Demon!
http://www.ziebart.com/ a rustproofing company. Had their own yellow or white plastic plugs to fill the holes they drilled in your car. They guaranteed the rustproofing to keep your car from rotting out. Hope they had good insurance...LOL.
Oh yeah, nice buggy...how many options on that fender tag...looks like a plain jane ride. Should be a keeper.
