Koenigsegg's may be illegal in the US (for now), but a Miami-based car tuner has just acquired the first Koenisgegg One:1. The AutoFirm acquired chassis number 112, which is the final One:1 and was displayed at the Monterey Car Week 2015. The incredible supercar is finished in white and has pure carbon fiber exterior components. The One:1 is the most track-focused Koenigsegg ever built and comes with a 5.0-liter twin-turbo V8 that produces 1,341 hp and can propel the car to 273 mph. There's no word on what the tuner has in store for the vehicle, but it's here.
