Hi Rory,

Both cars use dual clutch semi-automatic gearboxes, which are pretty slick-shifting, but Volkswagen's DSG transmission just edges it for smoothness and quickness. 

On the emissions front it's rather bad news I'm afraid. If you're buying 2008 model year cars then you're looking at emissions of 189g/km for the Mondeo 2.0 TDCi Powershift and 175g/km for the Passat 2.0 TDI DSG. That means tax of €750 a year.

It gets a bit better if you can spool forward to 2010 when the Passat's emissions drop to 158g/km so that means a tax bill of €570 a year. 

Just for reference, the Mondeo 2.0 diesel auto gets an official 39mpg while the 2010 Passat with DSG gets 47mpg.

To be honest, if you can live without an automatic gearbox you would be better to go for the 1.6-litre diesel versions of either car. Both have decent performance and much better economy and emissions. For instance, a 1.6 BlueMotion Technologies Passat gets 62mpg and has emissions of just 118g/km so tax of €200 a year.

Hi there,

Welcome to Ireland! I'd suggest you have a look for a Honda Civic 1.4 petrol automatic. That's probably the best balance between reliability (Civics are very reliable), economy and sticking within your budget. The higher road tax comes from the changeover to a carbon emissions based system in 2008. Prior to that cars were taxed according to their engine size, but the Civic's 1.4-litre petrol engine should keep your tax bills down to a reasonable level. Sadly, there's nothing you can do to change the NCT test - every car requires one every two years once it's more than four years old, and every year once it's more than ten years old. Again, the Honda will help here - they're really well built so less likely to develop problems that would cause you to fail an NCT test, as long as you look after it and keep it serviced.

Hi Rao,

At a rough guess that should give you a budget of between €10,000 and €12,000, which is healthy enough. If you've been a Toyota owner in the past I'm assuming you want to stick with something that'll be reliable so my first suggestion is an Auris hatchback. They're spacious inside, so pass the two kids test with ease and the 1.33-litre petrol version should be economical enough for your commuting style. 

Also consider a Honda Civic. If anything, Hondas tend to be even better built than Toyotas and while the Civic's avant-garde styling may be a bit of an acquired taste, its spacious and practical cabin is a boon for family life. A 2.2-litre diesel may sound like overkill but it's a terrific engine and has low emissions and therefore is cheap to tax. 

Finally, if you want something with a bit more space, how about a Kia cee'd SW estate? Reliably solid, and with that seven-year warranty, pleasant to drive and the estate version has a massive boot.

Hi Tom,

Very few, thankfully. Watch for damp carpets as the ventilation system filters have a habit of leaking and letting water into the cabin, and check too to make sure that all of the pipes and plumbing on the diesel engine are correct - there were some problems with them in that regard. There's also a recurring issue with the airbag warning light that seems to be more related to the light than the actual airbag, but it's irritating nonetheless. 

The CO₂ emissions for the 1.4 TDCi Fusion are 120g/km so it'll cost you €200 a year to tax.

Hi Mech,

There are few drawbacks to be honest. If you're importing the car from the UK then there is no drawback at all, other than the extra bit of legwork and travel needed to find and bring the car home. And of course you should consider potential difficulties with warranty, financing and trading in your current car.

If you're importing a Japanese model there can be a few issues to look at. Some parts are different, which can make repair and maintenance work a little tricker (and occasionally more expensive) and Japanese emissions laws are different too, so the car may need a tweak to the engine management system to pass the NCT emissions check. Helpfully, there are still several companies in Ireland that specialise in the importing of Japanese market cars and they'd be able to help you out with any of that.

Hi David,

Diesel particulate filter issues are common to all modern diesel engines and it's basically down to how the car is driven. It's part of why diesels aren't suitable for low mileage, short-hop drivers. 

The Mazda issue appears to be down to the fact that the diesel particulate filter warning light double-jobs as a warning light for other exhaust and emissions issues, meaning that fixing or replacing the filter might not be the whole story. Essentially, if you've got this problem, it's best sorted by a trained and informed Mazda mechanic, as they can interrogate the engine's computer in detail.

Hi Alanna,

I reckon the Qashqai +2 might be the best one to go for. The extra seats are pretty small but the boot on the +2 is simply massive when they're folded flat, so that's helpful when you're lugging around two small ones and their various chattels. Don't worry about running costs too much - the Qashqai looks like an SUV but it's really a hatchback with attitude and the 1.5 diesel engine is reliable, economical and has reasonably low emissions too.

That Toyota 1.4 diesel you mentioned would indeed be much less powerful than your Mazda's engine - it's about 20hp down and noticeably so. Volkswagen Jettas are indeed reliable, but I reckon that the Nissan would be slightly more so, so make that your first choice.

Hi Michael,

Well, it kind of depends on the car. If you mean something along the lines of a Hyundai i10 or even a Peugeot 208 (ok, so that one's a 1.2 but still...) then the answer is not much. Fuel economy should work out at around 50mpg depending on how you drive; emissions should be under 120g/km; and insurance should be dirt cheap.

If you're talking about an older model, the waters are a bit muddier. Smaller engines generally mean lower running costs but there are cars out there with underpowered smaller engines, and you have to spend so much time ragging them to keep up with the flow of traffic that your fuel consumption goes through the roof.

Expert answer

Hi Frank,

The registration you provided is for a 2011 Mercedes-Benz ML 300 CDI BlueEfficiency with an automatic gearbox. That falls into the emissions band 191- to 225g/km, which costs €1,200 per annum to tax.

Expert answer

Hi Joe,

The last-generation S60 got a bit unfairly hit by various Irish tax regimes (it never had an engine under 2.0 litres for instance), but it's actually a cracking car - well built and superbly comfy, as Volvos tend to be. Keep an eye out for minor electronic glitches (the cruise control and electric windows seem to be vulnerable points) and if the engine is 'lumpy' when you're switching it off, you're looking at injector issues - expensive ones.

In terms of day-to-day running costs, it should do 44mpg with a manual gearbox (a little less with the optional automatic) and emissions of 175g/km mean you can tax it for €750 a year. That's pricey, but better than buying a pre-2008 model (2008-2009 was the last full year of production) when the engine capacity would land you with a €1,034 tax bill. One running cost to keep an eye on is front tyres. The S60 is quite nose-heavy and has a massive turning circle, things that tend to banjax the front boots. Check any potential purchase for worn rubber and budget for at least a new set every year.
