What Car? says...
There are big cars, there are really big cars, and then there’s the Mercedes GLS. This 5.2-metre long, 2.0-metre wide behemoth is designed to seat seven people in comfort and is the flagship of Mercedes’ extensive SUV range – think of it as an S Class SUV, if you will.
As far as rivals are concerned, the GLS is closest in concept to the 5.1-metre long BMW X7. However, as a prospective buyer, you might also want to consider (slightly) smaller seven-seaters such as the Audi Q7, Land Rover Discovery and Volvo XC90, or if you only need five seats, the full-fat Range Rover.
You can even specify your GLS with an off-road package if you want to venture off the beaten path – although, let’s face it, cars of this type are rarely asked to tackle more than a slippery National Trust car park.
In this review, we’ll look at everything from what the Mercedes GLS is like to drive, to how practical it is compared with rivals and how much it will cost you to run. Or, alternatively, to see how much we can save you on a new GLS, check out the deals available through our New Car Buying service.
