It’s all over car news websites and it’s all over Twitter: Porsche has unveiled the 911 R. It’s a car for the purists, says Porsche, with a naturally aspirated 493bhp 4.0-litre six-cylinder engine, a 201mph top speed, and a manual gearbox. Porsche has listed it at £136,901 – but it’s worth a lot more.

No matter what the list price of a car is, it finds its true value after a year in the market place. For example, the Range Rover Evoque has it right –£40,000 new, £35,000 a year later. By contrast, BMW got it wrong with the M6 – £100,000 new, £50,000 a year later.

With the 911 GT3 RS, Porsche got it wrong – but the opposite to BMW. Porsche lists the GT3 RS at £131,296, yet it has the performance and desirability to match a Ferrari 488, McLaren 570 and Lamborghini Huracan. The GT3 RS is, essentially, a supercar, and that’s why its true value now matches its rivals at £265,000.

Plus, it’s buoyed by the increasing value of older 911s (930, 993, 996 and 997) – in fact, we’ve just sold a 997 GT3 RS for £150,000.

The 991 911 GT3 RS has what’s likely to be one of the last incarnations of a high-revving naturally aspirated engine. I know in many years to come I’ll be telling my grandkids about the way its engine used to scream at 9000 revs, while they’ll look at me, with both confusion and concern, and say: ‘But, what’s an engine, and why didn’t the car drive itself?’

And so we bring ourselves back to the 911 R. It has a similar spec to the GT3 RS, but it’ll be even more sought-after. Production is limited to just 991 units, its name pays homage to the road-homologated 1967 911 R which raced in the Targa Florio, and it’s got everything you want for driving joy.

Is its value really £136,901? No. Could it be worth quarter of a million? Yes. In 10 years, could it be worth half a million? Definitely.
