With every iteration of this McLaren, it gets better. At first it was rewarding yet frustrating, but with every modification or model update, the rewards grow and the frustration dims.

Now this is one of the finest driver’s supercars you can buy. It rides with astonishing deftness on the road yet can be tied down on a circuit and lapped, repeatedly, with the kind of commitment, absence of fade and ability to not cook its own consumables that is reminiscent of a Porsche with a ‘GT’ tag, or even McLaren’s own P1.

So why no final half star? There are sufficient areas we’d still look at to improve – its behaviour in long corners where you can’t brake to the apex, for example, and the rather flat quality of the sound emanating from the exhausts.

It would also be gratifying to see McLaren at least experiment with an active mechanical differential for that last bit of limit adjustability.

But the good things are very good; if we could give the 650S Spider four and three-quarter stars, we would. It is the best convertible supercar money can buy.
