So what do you really need to know about the Mercedes AMG GT S? Well, here’s my tick list of things that you might not discover from an hour-long test drive…

The seats are ridiculous hard! Trust me, I’ve had passengers of all shapes and sizes in the GT S. And NOBODY has got out without commenting on the silly, race-tuned seats. It’s supposed to be a grand tourer. My hips are aching as I write this. Top of your options list should be a couple of soft scatter cushions.

The upright infotainment screen really doesn’t disappear into the dashboard! You know it’s fixed in that upright position but trust me, you will still try and push it away. Yep, it’s that incongruous.

Mind the gap. The doors are very heavy. No surprise in a car this size and rather reassuring BUT they do need a good slam.

The auto dip/full-beam system is lazy. I know it’s been an Easter Bank holiday but why do they take so long to dip in the face of oncoming traffic? Wake up in there!

Luggage space is minimal. On top of that, the door pockets are virtually pointless because they are so narrow and made of stretch material. You need two hands to insert something – not advisable at speed.

On the up side – it’s way better looking that a Porsche 911, will win more admiring glances and sounds fantastic. As a driver’s car? Well, it still lags behind the user-friendly Porsche – and the brilliant McLaren 540 is only a few bucks more…

A nice problem to have.
