What exactly would a "mule" be? Would there be any way to tell by looking at the car that it was one? Niki
A mule is a fully built car before they go into production. They were and are used as real world test vehicles. There's now way to tell if it was a mule. Most get destroyed due to legal issues. But some mules slipped through the cracks and never saw the crusher.
Well, there is a way to make an educated guess about a mule. You look under it for, NO, just kidding! Really, you look at the PHS and see where it was delivered. Sometimes there is even a hand written comment on the sheet.
