Yeah i'm sure they did. They actual had a car that was on display at the 2017 Geneva Auto Show, it was a highly customized Agera RS called the "Gryphon", long story short they had crashed it a couple months later during its shake down testing. It was for a customer in LA, he later said that Koenigsegg was going to build him another car which was even more customized, and Koenigsegg was going to rebuild it and use it as their new test mule for the company.
