This is a rather interesting Koenigsegg we have here, it's the only one of it's kind in the world so far, but another two will soon join it. The car is built as a last goodbye to the successful Agera RS model of which all 25 models sold out within 10 months. Now the first ultra-rare supercar (or megacar as Koenigsegg likes to call it) has made it's way to the open market, recently being listed for sale at James Edition. If you're in the market for rare and exclusive cars, this is the spot to visit. A single trip there could bankrupt even the wealthiest folk.

We've seen the "normal" Koenigsegg One:1 on sale privately, at some ridiculous prices too, which means those seven (only six were sold to the public) cars have been a bit of an investment for their owners. This exclusive one of three car costs more than the One:1 and has a few differences to make it that little bit more special. Are the differences worth the premium? Well yeah, the differences work just right. On the One of 1 there's now a twin blade, top-mounted rear wing, an air intake on the roof, a custom front splitter and a 3D-printed twin-exit titanium exhaust tip featuring 'One of 1' text to match the other One of 1 badges.

The best part is that fantastic custom designed paint finish with partial clear carbon; it simply oozes appeal. The performance specs of the One of 1 are same as the One:1, the bonkers twin-turbocharged 5.0-liter V8 that produces 1,341 hp and 1,011 lb-ft that can take the car to an insane 186 mph in just 17.95 seconds. The other Final models will be built for delivery towards the end of 2017 and we're keen to see what price they will find their way on to the market for. We also hope that their owners will want to show them off like they deserve to be.
