Both feature interiors with intricate marquetry that took 250 hours to create.

Think the Bentley Bentayga is expensive? Well, British Range Rover tuner Overfinch has created a pair of one-offs that make the Bentley look like something you’d find in a bargain bucket.

According to Overfinch, it set out “to create a Range Rover of unparalleled design and craftsmanship” in the Manhattan (in black) and London (in blue) editions. The company claims hundreds of hours were spent building the cars, including 250 on the interior marquetry alone.

That marquetry is an Art Deco depiction of the skylines of Manhattan and London. Over 5500 pieces over abalone shell, stainless steel, and five types of veneer were hand cut and laid into the American burr Walnut background, then sand-shaded to give a sense of depth and shadow. The result may be an acquired taste, but is undoubtedly a stunning piece of craftsmanship.

The interiors of both cars have been completely reupholstered in quilted Bridge of Weir leather - Ivory with Ebony detailing in the Manhattan, and Cirrus with Navy detailing in the London. They also feature machined sills plates and Overfinch Limited Edition rotary dial inserts.

The exteriors, meanwhile, both feature full Overfinch bodykits including deeper bumpers and side panels, grille, side “gills”, and rear spoiler. The Manhattan rolls on 22-inch Overfinch Equus wheels, while the London wears Tora rims of the same size.

Both cars started life as a top of the range long-wheelbase Autobiography model, with a 5.0-liter, supercharged V8 motor producing 510 horsepower (380 kilowatts), which can propel the 5313 pounds (2410 kilogram) beast from 0 to 60 miles per hours (100 kilometers per hour) in five seconds and on to a top speed of 155 mph (250 km/h).

The base car isn’t exactly cheap, then, costing £112,150 ($142,838) in the UK. But Overfinch has put a truly astonishing price on its work. The London edition is for sale right now in Overfinch’s London showroom bearing a sticker price of £249,990 ($318,369).

That’s about £90,000 ($115,000) more than the base price for a Bentayga, albeit about the same as a well-optioned example. Either way, it’s a huge price for an SUV, even a one-off.
