Hi Brian,

The diesel question is a particularly thorny one, mostly because we don’t have any firm guidance from the Government on what is going to happen with the taxation system. If anti-diesel taxes are brought in, then that will definitely have a serious effect on diesel used prices. For now though, all we can reliably say is that diesel is still popular outside the major urban centres and, for the most part, it’s still the best choice for the long-distance driver. I say most part, because hybrids are improving all the time and such cars as the Kia Niro and Toyota Prius are well able to manage better than 60mpg even on long motorway hauls, while a Lexus GS 300h, for example, is every bit as frugal in daily driving as a rival diesel product.

Hi Derek,

As ever, it's very difficult to assess such things from afar and we recommend finding a good mechanic to look at it. It could be the CV joints, but it could just be a wheel out of balance too, so best have it looked at.

Hi Andy,

It’s not a waste, as such, but you do need to balance out whether or not it’s worth the extra cash to you. Yes, the 530d has a lot more power and torque, and is smoother than the four-cylinder 520d from a refinement point of view. Balanced against that, the 520d will easily beat the 55mpg mark every day, while the 530d will struggle to do better than around 45mpg, and you’ll be paying a bit more motor tax every year too. So, while we love the 530d, and its six-cylinder smoothness, the head clearly says buy a 520d.

Hi David,

How about a BMW 320i? Not as powerful as your 330d, of course, but a really lovely engine, and pretty frugal for all those long journeys. Of course, if you’re buying a year-old car then diesel is still a viable option, especially if you’re racking those miles up, so another 330d could well be a good choice. It’s Euro 6 emissions compliant, so even if there are some penalties for diesel models coming down the line, it probably (fingers crossed) won’t be affected.

There are some other options, of course. How about a Lexus GS 300h? Big, comfy, great for long journeys, and 40mpg+, plus you’re future-proofing yourself with a hybrid (not a plugin). The IS 300h is also a good bet, but is a touch small on the inside, hence we’d possibly try and spend the extra to the the GS. Here are a few reviews to read:

Hi Jonathan,

You've not told us the year, which is a key thing, here, as the current Avensis (first launched in 2009) uses a timing chain in its 2.0-litre diesel engine, but some versions of the previous version use a timing belt. The 2.0-litre diesel engine producing 116hp (engine code 1CD-FTV) made between 2003 and 2006 has a timing belt, for example, but the 127hp engine, made from 2006 to 2009 (code 1AD-FTV), has a timing chain.

The recommended change interval for the timing belt in that 1CD-FTV engine is 105,000 kilometres, regardless of time.

Hi Simon,

You’ll need to check the fine print, but in most cases the warranty will be a pan-European one, so it should be honoured in any of that brand’s official dealerships here in Ireland. The only exceptions are where a manufacturer might have a different warranty in the UK compared to Ireland (such as Toyota) or where, in some cases, one or more years of the warranty are covered and backed by the local dealer group, rather than the manufacturer.

Hi Sean,

I agree to a certain extent with this, but not completely. Rear-wheel-drive cars with their engines up front (as with your Mercedes) really struggle with traction in icy conditions, but front-wheel-drive cars are no better when it comes to braking and turning in the same conditions so if such a law was to be brought it, it really should apply to all cars, as winter tyres provide much more grip whether you're accelerating, braking or turning.

However, despite the crazy week we've had here in Ireland with snow and ice, long term weather stats clearly show that we don't get enough cold weather in most parts of Ireland (i.e. the temperature below seven degrees C) to warrant forcing everyone to change to winter tyres. Above seven degrees C, winter tyres are not as good as all-weather/summer tyres and they wear much quicker.

The Irish motorist already feels hard done by in terms of taxation and running costs so I don't think any government would bring this in here, but to be honest, I don't think they should, either. It really should be up to the individual. And that's coming from someone that has expereinced how brilliant winter tyres can be. Other opinions area available...

Hi Catherine,

It might be, but it depends on the dealer. Car makers aren’t allowed to set fixed dealer delivery charges for their models, as the authorities consider that an anti-competitive policy. So, dealers are free to set their own prices, and then to offer discounts on those as they see fit. All you can do is shop around.

Expert answer

Hi Aaron,

I'm afraid we don't have a way to do that. You'll need to contact a main dealer direct for that.

Expert answer

Hi Gabriel,

We had a worth with our contact at Cartell.ie and this is what they said:

"Unit Stocking usually points to dealer finance. These types of issues can often be resolved, but as with any amount outstanding on a vehicle Cartell would advise caution until the matter is resolved. A Cartell.ie report provides a contact telephone number and account reference number for finance markers in the UK - so the customer can contact the bank directly and look to clarify the issue. If you are still having problems ring Cartell.ie customer service team on 1890 252331 or 01 5241517 and they'll be happy to talk you through the steps."

Hope that you get sorted
