Top 5 One-Off Supercars Ever Made

Exotic cars are rare by nature, but one-off supercars exist in a league of their own. These are the machines built for billionaires, collectors, or purely to showcase a brand’s ultimate vision—never to be replicated. Whether commissioned privately or created as design statements, these cars combine jaw-dropping performance with unmatched exclusivity. Here are five of the most unforgettable one-off supercars ever made.

1. Ferrari P4/5 by Pininfarina

• Owner: James Glickenhaus

• Base Car: Ferrari Enzo

• Year: 2006

Commissioned by filmmaker and collector James Glickenhaus, the P4/5 was Ferrari and Pininfarina’s modern tribute to the iconic P-series race cars of the 1960s. It took the already ridiculous Enzo and draped it in a custom carbon fiber body that oozes vintage endurance racer vibes. Not just a styling exercise—this thing performs too.

2. Lamborghini Egoista

• Purpose: Lamborghini’s 50th Anniversary

• Base Car: Gallardo

• Year: 2013

“Egoista” means selfish in Italian, and this jet fighter–inspired Lambo takes that concept seriously. It has one seat. That’s it. Designed by Walter de Silva, the Egoista features fighter-jet styling, a canopy door, and enough LED lighting to land a plane. It’s not road legal—but who cares when it looks like this?

3. Bugatti La Voiture Noire

• Price Tag: ~$18.7 Million

• Base Car: Chiron

• Year: 2019

Literally translating to “The Black Car,” this one-off Bugatti is a tribute to the lost Type 57 SC Atlantic owned by Jean Bugatti. With hand-crafted bodywork, a 1,479-hp quad-turbo W16, and absurd levels of luxury, this is arguably the most expensive new car ever sold. And yes, it’s street legal.

4. McLaren X-1

• Commissioned by: Anonymous Client

• Base Car: McLaren MP4-12C

• Year: 2012

The McLaren X-1 is what happens when a client walks into Woking and says, “I want something completely different.” Inspired by everything from art deco styling to vintage Batmobiles, the X-1 is hand-built with a carbon fiber body that looks like it came from another planet. Underneath, it’s a proper McLaren—meaning it’s brutally fast, too.

5. Pagani Zonda HP Barchetta

• Made For: Horacio Pagani himself

• Base Car: Zonda

• Year: 2017

The final swan song of the Zonda—this is Horacio Pagani’s personal dream car. With its chopped-down windscreen, exposed rear wheels, and retro wheel covers, the HP Barchetta looks more like an art piece than something meant to hit the tarmac. But make no mistake: it’s powered by a 789-hp naturally aspirated V12. Only three were made, but only one was truly meant for Horacio.

One-off supercars push boundaries—not just in performance, but in design, craftsmanship, and exclusivity. They’re rolling proof that with enough vision (and enough money), anything is possible.
