Hi Patsy,

BMW offers three different diesel engines with xDrive four-wheel drive in the X3, the xDrive20d, xDrive30d and xDrive35d. The xDrive20d can be had with a manual or automatic gearbox and the official figure is 50.4mpg (5.6 litres/100km) no matter which transmission is fitted. The xDrive30d and xDrive35d are only available with automatic gearboxes and the official fuel economy figures are 47.1mpg and 46.3mpg respectively (6.0- and 6.1 litres/100km).

Those figures won't be obtainable in the real-world, obviously! We spent time with the xDrive20d during snowy conditions a few years back (read the full review here) and averaged 34mpg (8.3 litres/100km), though in normal conditions it should do a lot better than that. We also tested the xDrive30d (read that full review here), though apologies, but I didn't record the average fuel consumption figure at the time...

Hi Martin,

You're in an enviable position and, before going into more detail, we'd be very happy with any of those cars as an ownership proposition.

Personally, I'd be sorely tempted by the Evoque. There are plenty of colour and wheel options to change its appearance to your liking, it's much more of an occasion inside and it drives like a hot hatch (the chassis is very much road-biased, though it does well enough off-road when needed). Admittedly, certain versions of the BMW and Audi may be more economical, but I'd look at it very closely.

When the current BMW X3 came out it really took a leap forward from its predecessor in terms of comfort, quality and refinement, but between that and the Audi Q5 I may too be swayed by the fact that the Audi has had a more recent update. I also prefer how the Q5 looks. There's very little between them depending on which engines you're looking at.

The best advice is to go test drive each car for as long as possible, paying close attention to the specifications of the test cars.

In terms of automatic gearboxes, unless you're looking at a petrol Q5 (which I doubt!) or the high-performance SQ5 TDI model (fantastic) then the only option is the dual-clutch S-Tronic unit. This helps with efficiency and allows the driver more control when he wants it, but is not as smooth as a traditional torque converter gearbox, as fitted to the Evoque and BMW. They're both smooth systems, but the eight-speed item in the BMW is the most impressive, managing to minimise fuel consumption increases.

Hopefully that's of help, but come back to us if you need more

Hi James,

Mostly that generation Sorento is pretty well built, and the fact that it was a bit old-fashioned, even when new, means that there's generally less in the way of fiddly electronics to give trouble. Do watch for an issue with a seizing alternator pulley and an automatic gearbox that lets the car roll forward when in park, both of which should have been fixed under a recall. As always with a heavy car that may have been used for towing, keep an eye on the condition of the clutch (watch for slipping in gear on the manual model) and turbos (any blue smoke means it's on the way out).

Hi Mairead,

Pajeros are exceptionally rugged and reliable cars, as Mitsubishis tend to be. It’s an excellent tow car, with a maximum braked towing weight of 3,500kg, but if you’re towing something that big, remember that you will need a BE category licence if the weight of the car and trailer combined is more than 3,500kg.

Hi Ronan,

Thankfully the potential glitch list on XC90s seems to be pretty small, especially if you go for the diesel engine and the Asin-Warner automatic gearbox. Apparently most XC90 problems relate to the petrol engined versions, running a GM gearbox.

Make sure that the timing belt has been changed at 100,000-mile intervals. Check for outer-shoulder tyre wear caused by suspension mis-alignment. The top suspension mounts can be weak on the early models, but as the one you're looking at is a 2008, you should be OK, as Volvo replaced many under warranty. Wheel bearings can wear, so listen for rumbling noises and the brakes pads and parking brake mechanism are both prone to early wear.

Hope that helps; let us know how you get on.

Hi John,

Interestingly, you haven't given us a budget to work with here, so that means a whole world of possibilities looked to be opening up, and then you hit us with the sub-2.0 clause, which instantly shut them down again.

So how about these for some suggestions:

Kia Sportage: you'll get a 2.0-litre diesel 4x4 auto for €35k and it's as stylish and good to drive as you could wish for.

Want something a bit more premium? How about an Audi Q3? Very stylish, but a bit more pricey. €41k gets you a 2.0 TDI quattro.

Finally there's the new Ford Kuga. Bigger and more practical than either of the other two mentioned, you'll pay €43k for a 2.0 TDCi diesel with Powershift auto.

What do you think?

Hi Sean,

According to the official figures, the comparison in terms of combined fuel economy is this: the 520i gets 28.8mpg, the 525d gets 36.2mpg and the Lexus IS 250 gets 31.0mpg. A clear win for the diesel 5 Series there, but it's worth remembering that these figures are taken from laboratory samples and you may have to knock off as much as 25% to get the real-world driving figure.

Hope that helps

Hi Kay,

Quite a rare car that. In fact, we can only find a handful of other MINI One autos from that year for sale, which means your value should be in the region of €11,500. Possibly a little less if you're trading it in.

Hope that helps

Hi Catherine,

OK, so what you need here is something spacious (kids, even just the one, take up a heroic amount of space, as you know), something economical for all that annual mileage and something comfy so that your buttocks survive all that mileage. I think you should stay with the current rough size of car, as some of the best bargains can be found in the mid-size saloon segment.

First up is a Volkswagen Passat. Ideally, you'd get the 1.6 TDI BlueMotion version, a car in which we once managed to drive from Galway to Glasgow and back on one tank of fuel. Or, what about a Ford Mondeo? You'll easily get a 2.0 TDCi model for that money, and there are very few cars quite so comfy on a long journey. Even BMWs and Mercs can't always match the Mondeo for seat comfort.

Of course, if you fancy the high life, and are prepared to compromise on space a little, then there's the BMW 3 Series. You'll get a 320d or 318d for that kind of budget, but shop around to make sure you get one in a dark metallic, with leather and preferably an automatic gearbox.

Finally, there's the Mazda6. Bit of an unsung hero of this segment, it's brilliant to drive, spacious, good looking and you should be able to track one down with Mazda's excellent 2.2-litre diesel engine under the bonnet. Reliable as it gets, it should chomp through your annual mileage with nary a worry. Find the even more handsome estate version if you can.

Come back to us if you need help narrowing this down.

Hi Peter,

The low mileage on your car really helps, as most examples of the 325i on sale have considerably more on the clock. I'd say you're looking at a value of between €13,000 and €16,000, depending in spec, colour and whether or not your car has an automatic gearbox. A dealer will most likely pitch you about €12,000 on a trade in.
