At £360,000, which I reckon is more expensive than any other car built in significant volumes, shouldn't the Phantom be the best? I mean, it would be a failure if it weren't, wouldn't it?
Because if a Phantom owner drives the Rolls and you climb into, say, a Hyundai i10 - which starts at £8,995 and is one of the best city cars you can buy - you'll get to your destination at the same time, you'll stay just as dry, fit five people, carry almost as much luggage, park it more easily, find it's more agile, that it has a long warranty, a stereo, and one of the greatest gearshifts on any production car. Should the i10 not be the best car in the world, for being able to do all of that, for a fortieth of the cost of the Rolls?
Or there's the Volkswagen Golf R. Ah, lovely Volkswagen Golf R. It's all the things an i10 is, but more, because it's more fun to drive, faster, a bit more practical and refined, and so on. It's a terrific car and yet is still only £31,355. Should perhaps that not be the best?
Try that arithmetic with the Phantom? You can buy at least 11.4 Golfs for the price of a Rolls, but you could have 200 of them, and still none would ride as silently or smoothly as the Phantom. Conversely, cut a Phantom to a tenth of its size and it won't do what a Golf will. Logic, here, is no use at all.
Bentley Bentayga? Yes, it is expensive, but is given a harder, broader, brief to fulfill than, I think, any other production car. It has to be a capable 4x4, to tow 3.5-tonnes, and yet needs to be a luxury car too. Oh, but did we mention we also want to be a bit sporting, and have a 187mph top speed? That it does all of these, even though it costs upwards of £160,000, is remarkable. No other car does as many things, as capably, as the Bentley Bentayga. Does that not make it the 'best'?
And the truth is that however you present your argument, in fact, is how you define the best car in the world. There is no right, there is no wrong, there is only opinion. The best car in the world is indefinable.
Except that, obviously, it's a Porsche 911 GT3.
