Tim, there were a total of 4 IBM ZL1's built, both were show and press cats. The Corvette museum auctioned one off last year to a guy on the East Coast and GM held the other thr ee possible sale. I can confirm this with Scott if your buddy is really interested. Be a pretty cool car to own if indeed it is only one of four ever built. In essence he would be buying it for $35k. Not bad.
