With this in mind, Adrian Hearn visited luxury car dealer Broughtons to check out these two awesome vehicles worth nearly £2.5 million.

As I walked past a seemingly endless amount of £100,000+ Bentley Continentals and Aston Martin DB9s, I got to the front desk to ask the receptionist if Tommy was working.

“He’s in the supercar showroom,” she said.

It says something when a 202mph Bentley and 190mph Aston Martin aren’t classified as supercars, but these are no ordinary cars I’ve come to see.

The Koenigsegg CCX-R alone is worth £1.5 million– ten times more than the Bentley and Aston.

Which makes these cars closer in value to a Perodua Kelisa than a Koenigsegg CCX-R – and there’s a reason for this.

The last of six to ever be built, the Koenigsegg CCX-R is a super-limited hypercar powered by a 4.8-litre twin-supercharged V8 engine developing 888bhp – when using unleaded fuel. Fill it with biofuel and this power jumps to 1,018bhp.

With this oomph, the CCX-R will accelerate from 0-62mph (100kph) in 2.9 seconds, 0-124mph (100kph) in 8.75 seconds and all the way to a tested top speed of 254mph.

Christian Von Koenigsegg, the man behind the Swedish car maker, reckons the CCX-R will go faster than this and eclipse the SSC Ultimate Aero TT’s world record top speed of 257mph and lap the Top Gear test track two seconds quicker than the Gumpert Apollo.

But first of all he needs to find a track long enough to hit 258mph on – and then he needs to hand the keys over to The Stig.

So what’s the difference between the CCX and CCX-R? The attention to detail is incredible. For example, the carbon fibre paintjob took 600 hours to complete – after the standard spray.

And the body has been modified to provide 3.5 times as much downforce, increasing stability at speed and through the corners. The 335mm wide rear tyres have been specially designed for the CCX-R by Michelin to cope with lateral G-Force levels of 1.5.

As this particular Koenigsegg is the sixth of six to be built, this is the last chance for a super-rich car lover to get their hands on an unregistered CCX-R with no miles on the clock. As a result, nobody is allowed to drive it. Bruno Senna, the nephew of F1 legend Ayrton, was given special dispensation to drive it for a TV show but that’s been withdrawn now just to keep this model that little bit more exclusive.

I was fortunate to get in the driver’s seat and give the CCX-R some revs. It might have been in neutral but the sound and feel gave me an indication of what this hypercar is capable of.

As I floored the right-foot pedal I heard an almost deafening sound coming from the centrally-mounted exhaust system. People looked around wondering what was going on – it’s truly immense. 

But if you’re seriously interested in the Koenigsegg you’ll need to put down £100,000 as a deposit – just to test drive the 400kph monster. So now you really want it and you’ve either got your card, chequebook or truck load of fifties out to pay for it, can you just drive it away? Not really, and this is when it gets interesting.

Broughtons will fly you out on a private jet to Koenigsegg’s headquarters in Sweden which, fortunately, is on an airbase. On landing, you’ll meet the head honcho Christian Von Koenigsegg who will then take you onto the track in a Koenigsegg to show you what it’s capable of.

And then he performs his party trick. On a straight, Mr Koenigsegg will floor it all the way up to 200mph without his hands on the steering wheel and then slam the brakes on – again, without touching the steering wheel – just to demonstrate the car’s stability.

After undergoing training in the Koenigsegg, Broughtons will then fly you back to England – and then you can get your hands on the 254mph+ Swedish hypercar. But if you’re interested in the CCX-R, you’ll need to be quick. It’s only in the country for a short time – and, after production as ended, there will be 50 times as many Bugatti Veyrons worldwide as there will be CCX-Rs, so this truly is a super-rare supercar.

But if it’s not stratospheric power you’re looking for Broughtons also has a Bentley Continental GTZ styled by Zagato for sale.

Zagato is an Italian coachbuilder which specialises in remodelling luxury cars. In this case it has taken a Bentley Continental GT Speed and hand built a whole new body with the car now sporting a huge front grille and provocative rear end. Just nine of these Zagato GTZs will ever be made.

The attention to detail on the GTZ’s body is phenomenal with the rear lights costing an amazing 100,000 Euros to engineer.

Under the bonnet remains the 6-litre W12 engine, which develops 600bhp and 553lb/ft of pulling power – giving the luxury tourer a 0-62mph time of 4.5 seconds and a top speed of 202mph.

But while the standard Continental GT Speed is £137,500, the GTZ Zagato will set you back £900,000 – that’s the price of exclusivity. And it’s only in the country until Friday so you’ll need to be quick if you want to be one of nine people worldwide with a GTZ Zagato.
