Hi Ollie,

Generally speaking, you should be OK, as that 30-min run each day should be enough to keep a DPF hot enough to clean it out, but that’s if and only if that 30 mins is all run at high-ish speeds, say above 80km/h most of the time and in a lower gear. If you’re spending a lot of time in stop-start traffic, I think a petrol option might still be the better one. Mazda’s 2.0-litre petrol engine can be a bit thirsty, but the 1.4 TSI option in the Passat and A4 is a very frugal engine, and still has peppy performance.

Hi Fuad,

Hellish in both respects. The RX-8 is a terrific car, and was always one of our favourites, but they do suck fuel pretty badly. If you’re able to keep it above 25mpg on average, you’ll be doing well. Insurance is pricey because, even though the engine has a swept capacity of just 1.3 litres, it’s still a 190-230hp rear-drive sports car, and no insurer is going to be fooled by the engine capacity in this case.

Hi Tom,

As the Volvo V50 is based on the Ford Focus it has proven to be quite reliable. The V50 was the subject of two recalls, including a potential fuel leak and an issue with the windscreen bonding. Ensure that any car you're considering has had those items seen to. Isolated issues with the parking brake and the electronic ignition key have been reported too, though you'll soon pick up on that during a test drive.

Owners report that the suspension and electrics give the most problems so test every switch and listen carefully for knocks in the suspension.

Hope that's of some help

Hi Andrew,

You're in an enviable position. I'm going to go on the assumption that four-wheel drive is a must-have (though a rear-wheel drive car on winter tyres is as good as a 4x4 without in terms of stopping and changing direction as well as traction...) and given your comment on fuel we'll say it has to be diesel too. Don't worry, there's still fun to be had.

The 3.0 TDI V6 engine found in certain Audi A6s and A8s is a gem and partnered with quattro four-wheel drive seems made for you. The equivalent rear-wheel drive BMWs are a little more engaging, and the 330d/530d's engine is also fantastic, though we suspect you want four-wheel drive. Try a 535d out for size and you might change your mind and invest in winter tyres instead!

As much as we admire the X5 and Touareg, and they're good value on the used market at the minute, we can't help but feel they'll be just as difficult to sell on in a few years.

Another excellent alternative to the (quite common) Audi A6 is the allroad quattro version, based on the A6 Avant. Seems to tick all the boxes.

Let us know if we're on the right track here.

Hi Martin,

There were actually some significant mechanical changes for the Type-S, including wider-track rear suspension, an upgraded interior and a more aggressive body kit. That said, it’s still not THAT sporty, and a regular Civic is near enough as good to drive. The 2.2 diesel is an excellent engine, with good economy and very solid reliability. As for an ‘air energiser’ I’m guessing this is some kind of aftermarket add-on? Beware such things — they tend to promise much and deliver little, and usually aren’t worth the money.

Hi Jim,

There's no doubt that the Range Rover Sport (like all big SUVs) are harder on their tyres and brakes than an average car. Parts aren't cheap either and fuel consumption, even on the diesel models, is relatively high - though again, normal for the class.

Early examples were the subject of three recalls concerning brakes, the transmission and rear seat belt buckle, but once the car you're looking at has had those things recitified there shouldn't be an issue. The Range Rover Sport has a below average reputation for reliability, but we know people with faultless examples as well, so perhaps some buyers have been unlucky. Issues seem to come mostly from the electrics and the suspension so check everything is in working order and best to have some form of warranty from the dealer.

If you need more detailed help please do get in touch.

Hi Jonny,

In general this is a reliable engine and car, though there are a couple of known issues. These include the fuel sender in the tank and the variable geometry turbocharger actuator. The former you'll only spot if you know the fuel readout is wrong. The latter will be indicated by loss of power and the car going into limp home mode. This can often be cancelled by restarting the car so take as long a test drive as you can. No harm asking whether the seller has had either issue either and it's vital to have a full service history on this car.

Let us know how you get on.

Hi F D,

As discussed via email, the dual-clutch transmissions are usually far more efficient, resulting in lower emissions and fuel consumption. They also offer a more 'engaging' driving experience if that's what the driver wants. However, they can also be jerkier to drive than an old-school automatic, so we'd always recommend buyers to drive both to form an opinion of their own.

Hope that helps with the buying decision.

Hi Lorraine,

The 1.6-litre TDI engine is available in either 85- or 105hp outputs both of which have an official combined cycle consumption figure of 4.5 litres/100km (62.8mpg). The 105hp version is also available in BlueMotion trim with its longer gearing, unique bodystyling and other tweaks allowing for fuel consumption of 3.8 litres/100km (74. mpg). By way of comparision the 140hp 2.0-litre TDI Golf returns 4.8 litres/100km - or 58.9mpg in old money.

So while less powerful the 1.6 TDI is more efficient. All of the 1.6 variants also qualify for Band A tax of €160 whereas the 2.0 TDI is Band B, costing €225 annually. 

Just to throw a spanner into the works; over shorter journeys like the ones you outline a petrol powered model may actually prove to be more economical due to the time it takes a diesel engine to heat up and reach ideal operating temperature. And of course it will be cheaper to buy in the first place.

If you would like to discuss this further let us know.

Hi Juls,

The official fuel consumotion of the E90 BMW 316i is 5.9 litres/100km - or 48mpg in old money. This model actually received a mid-life update during 2008, but the upgrades were cosmetic and had no effect on fuel economy.

We hope this helps
