Hi Lisa,

You're better placed than us to answer that question, as it really depend on your driving style, the road conditions, how heavy traffic is, the type of road and how full the car is.

Saying all that, the official combined consumption figure for that car is 3.7 litres/100km (76.3mpg) and it has a 53-litre fuel tank. So that means 358 kilometres. The 'combined' figures can be a little misleading though, as they don't relate to the real world.

We'd estimate 250 kilometres on average for that car.

Hope that's of some help.

Hi Teresa,

We spoke to Volkswagen and I'm afraid there's no permanent way to switch this off that it recommends. You'll just have to do it manually each time you start up if it bothers you.

From our perspective, this feature is becoming more and more common and we think it's a great idea. If all cars on the road used it think how much fuel could be saved in town. Likewise - and in contrast to what you've said - noise pollution would be reduced overall thanks to the lack of engine idling noise at traffic lights.

Don't worry about the starting motor wearing out either, as most cars with stop-start have heavier duty starters, along with systems to monitor their condition and prevent it being over used.

Hi Kieran,

Nice position to be in! We're a little puzzled at the shortlist, but each to their own. I'm sure you know that the Beetle won't be a patch on the Boxster in terms of driving thrills and the Porsche trumps the SLK on that front too.

However, if your priorities are ease of repair, etc. then the Beetle seems to be the obvious choice, as there are loads of Volkswagen dealers around and a new car won't need much doing to it anyway.

Saying that, the Mercedes and Porsche are quite reliable and you have a choice of Mercedes-Benz service centres. While there are no official Porsche service outlets in Cork that we know of, as resale value is not of importance to you I'd suggest you get the number of a recommended mechanic. They'll do just as good a job with a more personal service. Get in touch if you need help on that.

Personally, I'd have the Boxster. Though of course I can understand the lure of the new car. The SLK is a distant third place.

Let us know how you decide - and if you need anything else.

Hi Ciaran,

You can't go too far wrong with a good Nissan Micra or Volkswagen Polo, even at that price. They are reasonable to insure, pretty reliable and the Micra in particular is great on fuel. We'd stay away from the Daewoo Lanos and though the Fiat Cinquecento is bursting with character they can be troublesome. Others to consider are the Suzuki Swift and Volkswagen Lupo.

Come back to us with a shortlist if you want and we can help further.

Hi Justin,

It's not surprising to hear that the car won't go off-road - few do!

In terms of safety, the 2005 Volvo trumps the Discovery with a better Euro NCAP crash test rating.

The Volvo has a marginally better reliability record too, though most Discovery problems (affecting electrics and software) seem to apply to individual cars. Saying that it's worth ensuring its air suspension is in perfect working order. On the XC90 the injectors can play up, and they're expensive to repair, so get suspicious if the car doesn't start quickly.

Evidence points to the Volvo having the lower running costs too, with slightly better fuel economy and of course lower annual road tax due to the smaller engine. Maintenance will be costly enough in both cases, as could be insurance.

In cold hard facts it looks like the Volvo wins this battle Justin, but we'd not be put off the Discovery so easily - it's a great all-rounder as well.

Let us know how you get on.

Hi Patrick,

On its own, the RAV4 2.0 D-4D is a fine car, with loads of power. It has plenty of low-down torque for towing too, though how heavy is your caravan? The manual Santa Fe has a higher towing capacity and it's a heavier car too, which will help in certain situations. Added to that, the Hyundai has more power and torque - (assuming you're talking about the newer 2.2-litre model) though obviously you pay for that with fuel consumption and tax.

Both cars have a good reputation for reliability though in fact it's the Toyota that has some history of issues - particularly with RAV4s used as tow cars. Apparently early versions (pre-2003) had transmission problems, though we'd hope the 2005 model is better.

Still, based on what you've said, we reckon the Santa Fe is the better bet in this instance, especially the newer model launched in 2006.

Let us know how you get on.

Hi John,

As discussed via email, you need to determine that a) the electric fuel pump in the tank is working and b) that fuel is getting to the engine. These are intricate jobs that only a qualified mechanic should attempt. Given that your car was rear-ended, it's highly likely that the issue is related to the fuel pump in the tank.

Failing all that get an auto-electrician to go through the relevant fuel pump relays and fuses.

Hope you get sorted.

Hi Anna,

As you're doing double the average annual mileage, and it's on motorway, we'd thoroughly recommend the diesel. It should save you a fortune on fuel, though of course you'll have to pay more in annual road tax. The downside is that you're likely to find that the 2.0-litre diesels within your budget have high mileage on them already. Seek out one with a perfect service history and as low a mileage as possible - and get it verified by Cartell.ie.

Hope that helps

Hi Sherif,

The newer 1.4-litre TSI engine is superior in every way. It produces a little more power, but way more torque across the rev range, making it faster and actually more efficient too so it emits less and uses less fuel.

Hope that helps.

Expert answer

Hi Richard,

Lots of potential reasons for this. Very first thing I'd look at is tyre pressures. Are they all even and to spec? Are there any other issues with the tyres you can see? Uneven wearing, etc. If no problems with pressures I'd suggest getting the alignment checked. If it gets knocked out (relatively easy to do with a pothole or kerb) then there could be more friction causing heavier fuel consumption.

Come back to us when you've checked that.
