For Big V8 petrol makes a great noise and gets the GL to 60mph in a quite phenomenal 6.5 seconds. Smooth, refined and massively equipped as standard.

Against The fuel consumption is punishing even if you’re gentle, so the turbodiesels make more sense. Very expensive and lacking the beautiful interior of its Range Rover rival.

At this price the GL needs to feel more special inside than it does. Petrol engine might be fast but it’s very thirsty. A no-brainer unless you own an oil refinery.

Buyer's notes

Target Price team says:

One for America only you might think, but the Mercedes GL isn’t quite as cumbersome in the UK as you’d expect. It might be long and tall but it’s not as wide as some in traffic, although width restrictors will still cause a quickening of the pulse. For its size it’s actually remarkably civilised to drive with surprisingly contained body roll and decent ability in the bends.

Two engine choices are offered, all mated to automatic transmissions and some pretty serious off-road equipment – all GLs come with hill descent control, locking differentials and low-ratio gears. That makes it a very able performer in the mire, not that owners are ever likely to find out.

Spacious, refined and comfortable the GL's size means even with the two turbodiesels you’ll struggle to manage sensible economy. But if you need a big, useful premium machine that’s not a Range Rover then it's worth consideration.
