You do sit up higher. I have my seat set as high as it will go as I have dodgy back. This makes it a lot easier to get in and out of the car. I'm 5ft 7in and my head is nowhere near the ceiling.
Sitting up higher gives you much better visibility, which I've really noticed on the M25 in the dark. I can see the tail lights of the cars way ahead, whereas when I drive my wife's Fiesta I can't see as far ahead.
Compared to an X5, Q7, Ranger Rover etc... you're low down, but compared to the majority of UK saloon type cars from Audi, BMW, Vauxhall, Peugeot, you're high up.
Like others have said… I was sold on the test drive and felt instantly higher up
Go grab a test drive.
