Variations on the ‘large 4x4 Merc’ theme because the GL is basically a larger seven-seat and tinsel version of the ML. Turns out that either is a pretty solid bet as an actual vehicle, but a little tarty for proper taste-mongers.
Comfort
Big and comfy and capable of steamrolling any pocked roads into submission. Can get a little wallowy if you decide to attack a set of hairpins, which has a direct effect on the colour-pallette of rear-seat passengers, but otherwise long distances are no problem.12 out of 20
Performance
The M-class comes with a 3.5-litre V6 petrol with 272bhp, a 5.0-litre V8 with 306bhp or one of a pair of diesels with either 190bhp or a more respectable 224bhp. The GL adds a 420 V8 diesel with 306bhp and a more powerful 5.0-litre V8 petrol with 388bhp. To be honest, only the base diesel is really an issue -the rest can motivate the big Mercs with ease. If we're being wish-listed for the real world then go for the big 4.2 V8 diesel.14 out of 20
Cool
If you're a footballer's wife then they probably look quite attractive, but the truth is that you can go cheaper and have as much space and prestige.9 out of 20
Quality
Unlike early M-classes, both the GL and M feel very solid. There's a fabulous feeling that Merc have started spending money on the bits that matter - and a decent interior is very important in this sector.14 out of 20
Handling
A Porsche Cayenne or BMW X5 both drive much better, but both the ML and the GL ride well and manage to get around corners without falling over. The ride compromise is more comfort-orientated, and you'll never forget that this is a tall SUV from the old school. If you want to get muddy, then you need the ‘Off-Road pro' option pack. But then you'd look a bit try-hard.11 out of 20
Practicality
Obviously the five-seat ML is a little bit smaller than the seven seat GL, but it manages to feel spacious. If you're genuinely after lots of seats, then the GL is still a little tight for all-adults. Both have decent boots when seating five, with some 633-litres on offer with the seats up and a truly enormous 2020-litres when you fold all the bits down.13 out of 20
Running costs
Oddly enough, the V8 diesel M-Class isn't all that shocking from a fuel economy point of view. Both it and the V6 diesel are reasonable. But the petrols are horrendous and the CO2 figures on all of them are pretty shocking.
