+Comfortable ride, tidy handling, excellent engines including 320 CDI, plenty of safety kit, upmarket interior.

-Only has five seats, a BMW X5 is a sharper drive, expensive to buy new.

Insurance Groups are between 43–50
On average it achieves 93% of the official MPG figure

Life is full of compromises. Do you choose the Rioja because you like it, or the Chardonnay because she likes it, or settle in between for the Viura? Do you buy a small house near your work or big house 30 miles away or a medium size house in the suburbs? Do you go for a prestige 4x4 that's good off the road or one that's good on the road or one that's half good at both?

Until recently those were the choices you faced. LandRovers of all types (apart from Freelanders) were brilliant off the road but dismal on it. BMW X5s and Porsche Cayennes were the opposite. Mercedes MLs, being the first posh ‘lifestyle' SUVs, were neither. Only VW Touaregs and Range Rover Sports have proved surprisingly good wherever you point them.

With the new ML, Mercedes has decided that it won't make the decision for you. Instead, it sells the car in three different spec levels with three different wheel sizes, makes self-raising air suspension optional, and, for serious off-roaders, offers serious off-road gear as a factory fitted option.

Should I buy a high-mileage Mercedes-Benz ML?
"I currently have a 2013 Nissan Qashqai petrol. I've had it from new, but really want my dream car, which is a Mercedes ML. However, I can only afford a 2007 or 2008 model with high mileage, but been told that buying a high mileage Mercedes-Benz is not a problem. Is this true? "
The MB badge does not guarantee problem free and the ML is in fact an American car, not a German car.

Electrical fault with Mercedes-Benz ML
"I am having trouble with my 2010 Mercedes-Benz ML-Class. Sometimes when I turn on the ignition the electronics do not turn on and the car will not start when engaged. If I turn the key off and try again it may or may not work but it will work after a few tries. I noticed the problem about a month ago but it seems to be getting worse. Can you offer any insight? "
Reads like a bad earth to the glowplugs relay, or failing glowplugs. That's assuming it's a 350CDI, which most 350s are.

What's causing a satnav fault in my Mercedes-Benz ML 420CDI?
"I have a 2008 Mercedes-Benz ML 420CDI, which has had an intermittent satnav function for several months. After prolonged diagnostic testing at the local MB dealer they replaced the antenna at considerable cost, but the problem persists. It registers no satellites yet sometimes works well, but if I venture into an area the DVD cannot recognise, it then loses its place and is unable to recover its position when on a recognisable road. It is to go back in shortly for more investigation. I am beginning to run out of patience and I wondered if you had any idea what may be wrong. All other parts of the ‘Command’ system work well."
If it only spasmodically recognises satellites it may simply be working from its memory in the same way as it does in a tunnel when it can't "see" any satellites. So I think the aerial system is still the root of the problem.

Which winter tyres should I buy?
"I need to replace the tyres on my five year old Mercedes ML500 that does around 6000 miles per year. It currently has 285/45/R19 on the rear and 255/50/R19 on the front. I would like winter tyres as we live in a remote area but given low mileage find it difficult to justify holding two sets. My main dealer is suggesting Pirelli Scorpion Ice. Could I run these all year or is a compromise tyre available?"
To work well in this sort of size, winter tyres tend to be specialised. Something like Michelin Alpin AP3s, or, as the dealer suggests, Pirelli Scorpion Ice or Pirelli Sotto Zeros (but they are very expensive). I just don;t know of any all weather in that size. But worth ploughing through
