The McLaren 675LT remains one of the finest road cars produced by the British manufacturer but there’s a lesser-known hardcore variant of the 650S that is even more remarkable. It is dubbed the MSO HS and one example is up for grabs from an exotic car dealership in Dubai.

Also known as the 688, the MSO HS was capped at a mere 25 units worldwide and each came outfitted with unique options that could only be ordered through McLaren Special Operations. This listing from Tomini Classics states that this one-owner car has only been driven 114 km (70 miles).

Like the 650S and the 675LT, the MSO HS rocks a 3.8-liter twin-turbocharged V8, albeit one that was upgrated to 688 PS (678 hp). Torque was capped at 516 lb-ft (700 Nm) of torque while various weight-saving measures resulted in the MSO HS weighing 40 kg (88 lbs) less than the 675LT.

The most obvious modifications include a fixed carbon fiber rear wing, canards on the front bumper, front wheel arch louvers, and a roof scoop. This particular example is painted orange and sits on a set of gloss black wheels. Images of the interior show that the car still features the plastic wrapping on the floors and side sills that it had from the factory. Most interior surfaces are clad in black Alcantara but there is orange contrast stitching that adds some color to the cabin.

Tomini Classics states that the MSO HS comes with all its delivery inventory and accessories and all services are up to date, while the asking price is $595,000.
