Michael,
In spite of it's odd design, it could easily be a perfectly good chassis, I just do not know. I had seen these in IFG's shop around 2001 but did not pay much attention, except to quickly form the opinion that some kid was missing their swingset. Here is another way to assess the value of that package. A good body kit with glass is worth $10,000. Without the glass that same kit is worth about negative $2,000. Use that as a baseline and factor in the other parts.
