That's because it's actually a replica of a 1998 concept car.
Back in 1999, Jaguar released a concept car called the XK180 to celebrate the 50th anniversary of the XK. The car was shown at the Paris Motor Show, and came with a 4.0-liter supercharged V8 with four valves per cylinder. The engine produced a healthy 450 hp and 445 lb-ft of torque going out to a five-speed automatic and RWD. This concept car had many advanced features such as Computer Active Technology Suspension, a tunable, speed-sensitive steering system, and racing-style aluminum shock absorbers.
The XK180 was never anything more than a concept, but some ideas from it, like the advanced suspension, did get put into production on later Jaguar models. Jaguar may have never built this car, but there are now a few companies in the world that can build a pretty close replica of it. One of them is Dutch firm Autobedrijf de Koning BV. It claims to build the most accurate example that's based on an XKR and to the same specifications that Jaguar used in 1999. What is now being reported is that the company's first ever example is currently for sale on Mobile, with an asking price of 235,000 euros (around $272,000). Surprisingly, this is not all that bad for a one-off sports car.
We have seen plenty of cases where one-off creations can cost millions of dollars. Jaguar's own XE SV Project 8 had a price tag of $200,000, and the F-Type Project 7 was also pretty pricey. This replica looks almost identical to the real thing, and even comes with a stunning custom interior. The interior is usually the biggest letdown on replica cars, but on this car it's one of the biggest selling points. Some may consider this to be a bit pricey for a replica, but it isn't too bad when you consider what probably went into making it as close as possible to the original. This is honestly a pretty fair price for a very unique car.
