In its most basic £800k form, the Pagani Huayra is a properly exotic stop and stare sort of supercar. But there are people in the world who like their car to be their car: a one-off.

That’s where bespoke treatments come in. They’re automotive tailoring services that make your dreams come to four-wheeled reality. Pagani has one, Horacio’s infamous 1 of 1 treatment. And the car above, the ‘Pearl’, is the first Huayra to receive off-piste customisations.

Details are pretty thin. But as you can see, it’s had some new aerodynamic accoutrements added. Most notably, the twin, split rear wing that’s a throwback to the original Zonda S. There’s also a carbon snorkel that runs from the engine, up the back of the coupe and sits on the roof as well as a new front lip to improve aero like the BC.

Engine details aren’t outlined. But considering the upgrades that the BC received – the familiar AMG-sourced 6.0-litre V12 bi-turbo, turned up to deliver 789bhp and 811 torques and fed through an all-new seven-speed Xtrac automated manual transmission – are available, if you were building your ultimate car, you’d throw the kitchen sink at it wouldn’t you?

Inside, it’s still the beautiful cabin we know and love but customised with Pagani’s signature cream leather, bronze carbon and silver detailing specified by the customer.

Obviously with these kind of projects money isn’t talked about. But we’d guesstimate that the value of this kind of car is somewhere in the region of ‘A Lot’.
