Miller Motorcars is celebrating its 50 th anniversary with a special one-off supercar.

It’s called the JC9, and it’s based on the Porsche Carrera GT.

It was designed in collaboration with Jason Castriota, an automotive designer known for the Ferrari P4/5 and many others.

It’s not every day that a luxury dealership decides it wants to build a one-off supercar, but that’s what Connecticut’s Miller Motorcars has done here. It collaborated with automotive designer Jason Castriota on the JC9, which is based on the Porsche Carrera GT—and it looks like something that could have competed alongside the 917K from over 50 years ago.

According to the Instagram post announcing the car, which made its official debut last weekend, the JC9 is a "coachbuilt V10 manual supercar" that is "fully constructed out of carbon fiber." The car doesn’t look like the Carrera GT it is based on, but that changes when you look inside.
