A rare McLaren P1 prototype that first came across our radar in late 2017 is once more up for sale from Tom Hartley Jnr.

The P1 in question is special, as it is one of just 14 experimental prototypes built by McLaren to develop the P1 and one of only five to have survived. When we first wrote about the car being up for grabs in 2017, it had 323 miles (519 km) on the clock and is up for grabs once again, this time with just 353 miles (568 km) under its belt. It is unknown why the car is being sold for the second time, but it does allow anyone who missed out on ordering a P1 from the factory to get one in superb condition.

The listing reveals that this particular P1 prototype was initially used for the development of the vehicle’s transmission and Bosch injection system. It was later converted into the initial P1 GTR show car and displayed at the Geneva and New York motor shows in 2015. When its official development duties were done, the car was stripped back to its carbon fiber Monocage and built to the same specification as other road-going P1s.

According to the ad, the previous owner opted to have the car painted in McLaren Orange and also got the carbon fiber rear diffuser and rear wing. There’s also a small Kiwi badge on the rear grille and stickers which denote this car as being the XP05 (experimental prototype 05). Inside, there is a stunning combination of matte carbon fiber, gloss carbon fiber, black Alcantara, orange contrast stitching, and XP logos on the headrests.

It goes without saying that any hypercar, never mind a P1, doesn’t come cheap. Nevertheless, the £1,350,000 ($1,669,450) asking price seems quite reasonable, and development prototype or not, if we could, we’d snap it up in the blink of an eye.
