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 Marion,

Yes, pretty excellent really. The A3 is nice to drive, exceptionally well built and holds its value well. That 1.2 TSI petrol engine is also excellent, as long as you're not doing mega-mileage. Just be careful that you buy one with a full service history and don't forget that you can buy a Golf, Octavia or Leon that is mechanically identical for less money.

Hi Ger,

To be honest, I would just avoid that generation of Rio at all costs. They're not especially reliable (engines, suspension and ventilation systems all give trouble) and the 1.3-litre petrol engine is quite underpowered, meaning you have to thrash it hard to keep up with the flow of traffic, which wrecks the fuel economy. On top of which the cabin is small, narrow and made of some staggeringly cheap and nasty plastic and they're basically awful to drive.

That generation of Rio was really the last of the truly bad Kias, before the company started to make some really good cars. Go, if you can, for a second generation Rio, made from 2006 onwards in both hatchback and saloon form. They're much more reliable, quite nice to drive and decently economical.

Hope that helps

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 Sophie,

In this situation we'd advise you to get a second opinion. However, instead of going to a regular mechanic seek out an auto electrician near you - preferably one that comes recommended.

Let us know how you get on

Hi Helena,

I presume you mean the diesel versions of both cars? If so, according to the official figures, a Qashqai 1.5 dCi diesel will return 54.3mpg on average, while a Corolla Verso 2.2 D-4D will return 44.8mpg.

Hope that helps

Hi Keith,

The areas you have to check carefully on an E60 5 Series are the suspension and electrics. If there are any nasty noises coming from underneath, or if the steering feels anything less than precise and solid, you've got possible trouble. The run-flat tyres can also cause trouble, suffering from little air leaks that play havoc with the tyre pressure monitoring system. The iDrive infotainment system can also be wayward, sometimes taking as long as 20 minutes to boot up, but apparently post-2005 cars are far better in this regard. Finally, check all the electrical and electronic systems to make absolutely sure that everything is working as it should be, and don't even consider a car that doesn't have a full service history.

Hi Greg,

Yup, they're a good 'un. Ford's reliability record has been steadily improving over the past few years and there are no major reported issues for that generation of Focus. Just watch that a recall to fix a leaking fuel return pipe has been completed and, of course, make sure the car has a full service history. Oh, and as many of these cars will have begun life as company cars, that can mean that they've been well cared for and serviced regularly, but it can also mean that they've been abused by uncaring owners. Check carefully.

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 Chelsea,

This is not all that unusual on modern cars and is usually nothing to worry about. Take the oil dipstick out, clean it and put it back in. Then take it out again and inspect. If that has anything other than clean oil on it then walk away.

With a car that new you'd hope the dealer will throw in a warranty in any case so ask about that too.
