How do you turn a great car into an even better car? We wish it was as simple as just placing a GT4 badge on the car. The Porsche Cayman GT4 was officially introduced last week and the expectations of this car are very hihg. Chris Harris was one of the first to test this car. His test resulted in a great movie. Do you want to know what he thinks of the Cayman GT4? We recommend you to watch the movie!
