Built from 1992 to 1998, the McLaren F1 is one of the rarest supercars out there. Production ended with 106 units, seven of which were prototypes. The remaining 99 cars were split between 71 road cars (including five LMs and two GTs) and 28 race-spec GTR models.

All F1s are rare, but the race-spec variants are definitely harder to find. If you're in the market for one, Tom Harley JNR is now offering a rare GTR Longtail model from 1996.

It's basically the development model, so it's pretty much unique. It's also only one of two GTR prototypes in private hands, with the other owned by Nick Mason of Pink Floyd fame. The car was raced extensively in Japan back in the day, but it has been converted to road use by Lanzante and Gordon Murray Design, so it's fully streetable.

It’s sold complete with a huge spares package, including all parts to return it back to full race spec, plus a dedicated book documenting its history and road-spec conversion.

The race-spec GTRs were fitted with the same naturally aspirated, 6.1-liter V-12 engines as the road cars, but output was limited to 592 horsepower by a mandatory air restrictor. This was likely removed during the conversion, so the V-12 should generate the usual 618 horsepower.



There's no public pricing information about this car, so you'll have to call the guys at Tom Hartley JNR, but expect it to cost a few good million dollars. McLaren's F1s usually fetch more than $5 million at auctions and a rare example was sold for nearly $20 million in 2019. Chances are that this GTR Longtail costs well in excess of $10 million.
