Ironically, it would be a lot easier to get there fast if you already had an FXX.
Insane track-only versions of range-topping Ferrari hypercars became the norm very quickly. It's something we epected when the FXX K was announced, but the FXX of 2005 was different, it was a new thing. Based off of the Enzo, but using ideas and technology which weren't feasible in the road car, the FXX was offered through Ferrari's Course Cliente program, previously only used as a support system for privateer owners of Ferrari F1 cars.
The program offered storage, maintenance and transportation for the car to motorsports events the customer wished to compete in. Just 38 of these cars were built, and the one you see here, serial number 145369, was the first one ever built. It was only used three times since it was first sold in 2005, with maybe 3 or 4 hours of total track time on it. And its red and white color scheme is unique among FXXs. It is going up for auction by RM Auctions in Arizona right about the time that you're reading this article, and it is expected to go for between $1.6 million and $1.9 million.
