Hi F D,

Short answer? We don't know yet. Theoretically, petrol engines heat up much more quickly than diesel engines (mostly because they're less thermally efficient) and therefore shorter journeys are less of an issue in that respect. It just depends on how much heat you need to generate to clean the filter and for how long. I'm sure that car makers will claim, as they did with diesel, that the filters are designed to be maintenance free, but then we've heard that before haven't we?

Hi Mary,

Have you considered a Ford Focus? I’m not sure what the situation is in your area with dealers etc, but a Focus has terrific steering – firmly weighted, direct and full of feedback and feel, and it’s also comfortable and well made (although, as a bad-back sufferer myself I would always suggest as lengthy a test drive as possible to make sure you find the seats a good shape). Quality and reliability are also good, if not quite up to Toyota levels. Your budget should get you into a year-old, maybe 18-month-old model and the 1.0-litre turbocharged EcoBoost petrol engine should make for an ideal option for you.

Hi Barry,

We've blanked out the registration for the owner's privacy, but using the quick free check on Cartell.ie I can tell you it's a 2010 Citroen C5 VTR+ powered by the 1.6-litre (1,560cc) HDi diesel engine making 110hp. This car costs €280 a year to tax.

If you need to know the history of the car then you'll need to pay Cartell.ie for one of their more in depth reports.

Hope that's of help.

Hi Michael,

I’d avoid the pre-2010 Mercedes-Benz E-Class – it had no end of reliability issues. Your other two choices, the Mazda and the Lexus, make much more sense as both have excellent reliability. Both are also tremendously enjoyable to drive, and it’s worth keeping an eye out for a hybrid Lexus if your mileage is that low, and especially if most of your miles are in town.

Hi John,

Well, it depends of course on what Revenue decides the Open Market Selling Price is (and there's usually no predicting on that score...),  but they seem to be worth around €15,000 on the Irish market, so with 98g/km and 15 per cent VRT, that suggests a payment of around €2,250.

Hi Sheila,

Both should be reliable, with the Hyundai just edging it in that regard. As you say, neither will be cheap to run, but with your mileage your only major cost is going to be motor tax and at least you can budget for that. Do plan to take at least one longish spin a week though to allow the diesel engines to warm through properly or you'll be looking at big repair bills.

On balance I'd go for the Hyundai, but it would be well worth looking at something like a Ford S-Max or SEAT Alhambra, which have even more space and generally lower running costs.

Hi Carl,

Yup, a cracking car and that looks like a good price.

Hi Martin,

There are a couple of things to check - that engine needs a lower auxiliary belt change at around 120,000km so make sure that's been done. You need to be watchful for the diesel particulate filter clogging up and the return pipes for the fuel injectors can leak, so if there's a strong smell of diesel when you lift the bonnet, those will need replacing. 

Expert answer

Hi Carl,

Yes, theoretically you can run any diesel car on bio-diesel, but you need to be careful with where you're sourcing your fuel from - low quality bio-diesel can clog your injectors up.

Hi Chris,

It depends on the total spec of the vehicle but assuming it has the 1.6-litre diesel then I'd say around the €3,000 mark.
