Should you buy one?

Although the GLS can’t quite hold a candle to the BMW X7 and Range Rover, it is a compelling choice at the top end of seven seat SUVs. For a start it’s bigger than both of the aforementioned rivals, giving additional space for people or luggage. It also feels more natural to drive than competitors with four-wheel steering as the back doesn’t pivot round, although the downside is a larger turning circle.

We’d argue the GLS certainly makes for a better seven seat luxury SUV than the all-electric Mercedes EQS SUV. It feels better built for the most part, has more space and drives better, too. As for the Maybach and AMG versions, they are both overkill when a 450d Business Class is already brisk and plush, but their intended owners will no doubt appreciate the additional excess.

What we like

The acres of space and comfortable ride make it a great family hauler. All engines have plenty of punch, with the 450d standing out as the best blend of performance and semi-sensible running costs. Equipment levels are high, and the interior is more user-friendly than rivals that have moved away from physical controls.

What we don’t like

The 450d is thirstier than comparable X7s and Range Rovers, and we can’t imagine the petrol engines will be any better. It’s not as manoeuvrable as rivals with four-wheel steering, interior quality is disappointing in places and rivals have quieter engines.
