The Vilner Design Mustang GT is one of the most meta custom cars ever created. A Chinese Mustangs owner requested that the customization firm use real Mustang leather and hair in his car's interior. The sourcing of said materials was obviously difficult, and the company admits the use of horse hair will be controversial. The result, though, is a one-of-a-kind creation. The seats are leather and the horse hair is only present on the sides of the two front seats.
The Vilner Design Mustang GT also features a hand-painted cobra on the roof as a nod to the famous Shelby Mustangs, which use the snake for a logo. Other than the interior additions the muscle car has been left untouched. There's no word how much the Vilner Design Mustang GT cost to commission, but given the materials used it couldn't have been inexpensive.
