There are 959-look cars out there, so I doubt if a real one has been sitting in a parking lot for 5 years.
At the first Canepa tech session I went to years ago he had about a dozen of them. He likes to buy them from Japan.
He kept this black one. I forget the exact history. It was built for a Porsche race car driver. Porsche did not want to make it black because heat might delaminate the body panels.
