Unknown 10

Unknown 10 refers to an American Senna with a blue-tinted "visual carbon fibre" body. The brake calipers and front aero blades are finished in "McLaren racing orange".

The car was delivered by McLaren Newport Beach, which received the car before or on October 26, 2018. The dealership added a protective film to the exterior. It was present during the November 2018 "Supercar Show" at Lamborghini Newport Beach, an event which was hosted on the first Saturday of that month.
