A good example would be the 2 swiss cheese frame W31's that were built there in 1970. At least partially built. They wee pulled off the line at Body drop and pushed out the back door into an enclosed trailer and never heard of again.

Dave, where the heck did that come from? Would love to hear more about those W-31's.

As this hobby has grown, and with the internet, I find it amazing how many one-off or lightweight GM cars have surfaced. Just a couple years ago, the story broke about the 6 lightweight 65 GTO's that were shuttled out the back door with thinner than stock sheet metal. And quite a few years ago, another story was printed on a 69 Firebird that was built by PMD Engineering, where they installed a (new) 455 with round port heads, and cruised the streets "testing" the combo.
