The world's only road-legal Ferrari FXX has surfaced on the used-car market, listed for sale by a supercar dealer in the UK.
With an engine producing more than 600kW from a 6.2-litre V12, the Ferrari FXX was the most extreme creation to come out of the Italian marque's workshop when it broke cover back in 2005.
Based on the Enzo released three years earlier, the FXX is a lighter, louder, faster and, most significantly, track-orientated vehicle built on the same Enzo platform.
Classed as a "track day development prototype", the FXX was only ever meant to see action on closed race circuits - and Ferrari made sure that was upheld.
See the FXX isn't exactly a casual customer car; the car was only part of the experience for the approximate $3.5 million purchase price.
The real purpose was to give pre-selected customers a chance to sample cutting-edge Formula 1 technology while taking part in Ferrari's testing and brand development programmes.
So from 2005 to 2009, all 30 FXXs produced were housed at Ferrari headquarters in Maranello, owners were not permitted to simply trailer their cars home at the end of a days driving.
Rumour has it this was due to the FXX featuring technology and components so closely related to that used by Ferrari's Formula 1 team it feared eagle-eyed competitors would gain insight into its competitive advantage - but that was then.
Now with the programme wrapped up, anyone can own an FXX.
This brings us to the 2008 Rosso Corsa red example listed for sale in the UK, which isn't actually a FXX, it's an FXX Evoluzione. The Evoluzione model is the evolution kit developed as a result of the the FXX programme.
The upgrade packaged boosted engine performance, sharpened gear changes, tweaked the traction control system and lowered the car's aerodynamic drag.
With these improvements, engine output from the naturally aspirated V12 was increased from 603kW to 630kW, acceleration from 0-100km/h taken care of in 2.5 seconds, and reach a top speed of 400km/h in less than 40 seconds thanks to a gearbox allowing that shifts cogs in 60 milliseconds.
In 2015 this car was purchased by a private collector in the UK who somehow convinced Ferrari to make the car road legal - no small feat in itself.
With both parties in agreement, the FXX Evoluzione was sent back to the Maranello factory it once called home for the modifications required. Indicators, headlamps, brake lights, handbrake, nose lifter, softer suspension settings and ride-height control were all fitted by Ferrari technicians.
Instead of traditional wing mirrors that could disrupt airflow, three cameras were fitted on the outside of the body, one on each of the front guards and one on the roof acting as a rear-view mirror. The cameras relay a live feeds to three screens positioned on the dashboard.
Final modifications included swapping the slick tyres for treaded ones, fitting a new fuel system and number plates - after that, it met all the requirements of a British MOT (equivalent of a WOF) and could be used by the owner on their daily commute - which could be lively.
The asking price for all that prestige and performance - £3.25 million ($5.7 million).
