The special forces-themed makeover was commissioned by an appropriately anonymous customer.

We’ve seen many cars customized on a particular theme. Antonio Brown’s galactic Rolls-Royce Wraith, for instance. But the latest project from Bulgarian outfit Vilner has a theme the like of which we’ve never seen before.

Vilner has given the interior of a Jeep Grand Cherokee SRT a comprehensive makeover, with a special forces theme. Specifically, the British Special Air Service (SAS) whose logo, together with the force's slogan 'Who dares wins', is embroidered on the front seat headrests.

According to Vilner, the identity of the owner is top secret, saying only that “the SAS logo is there for a reason.” My money is on it being Andy McNab, the novelist who specializes in tales of SAS's exploits. Exactly what the commanders of the SAS make of their logo being used in such a way is anyone’s guess.

Little in the Grand Cherokee’s interior has been left untouched. Carbon fiber inserts have been added to the dashboard, for instance. And areas that are usually hard, bare plastic like the bottom of the dash, transmission tunnel, A-pillars, seat bases, and even the seatbelt buckles have been trimmed in alcantara.

The ceiling, too, has been retrimmed in red alcantara and a black “high quality material.” The black and red theme is carried throughout the interior. Vilner says the red denotes “the missions of the SAS.”

It seems the car’s exterior and mechanicals have been left standard. Not that it needs any more power, the 6.4-liter HEMI V8 serving up 475 horsepower (354 kilowatts) from the factory. That translates to a 0 to 60 miles-per-hour time of less than five seconds, and a top speed nudging 160 mph (257 km/h). The styling, too, is already as butch and aggressive as an entire SAS regiment, so doesn't really need any further embellishment.

Even with a body finished in black, this Grand Cherokee SRT8 is nothing like as discreet and stealthy as the force is pays tribute to. But it's a bit of fun, which is all that matters really.
