Hi Avril,

Yup, if you're doing big mileage, then the fuel-sipping nature of a diesel is exactly what you need. I'd suggest a 2008 Hyundai i30 or Kia cee'd 1.6 diesel. Both are in your price bracket (just about - you may need to haggle), both are massively reliable, spacious, comfy and nice to drive. Hard to go wrong with either so just buy the best one of either brand that you find.

Hi Eamonn,

Not that we’re aware of. Like any modern engine, the SkyActiv 2.2 diesel is built to very fine tolerances, and needs regular care and attention. That doesn’t mean it’s fragile, just that it’s a good idea to keep an eye on the oil level, and make sure that the car is serviced, properly, according to schedule. The old days of using and abusing engines is gone.

Hi Susan,

Well, strictly speaking the Santa Fe isn't an MPV, it's an SUV (I know; Captain Pedant strikes again...) and that does have a pretty unpleasant effect on its CO₂ rating. A 2008 2.2 CRDi diesel Santa Fe emits 190g/km of CO₂ - enough to land you with a €750 annual bill. That aside it's a very fine car, with reliability, looks and practicality all on its side.

If it's lower CO₂ you're looking for though, you may well have to consider an MPV. The Ford C-Max is only capable of taking three child seats once you get into the current model, and that may still be too pricey for you. Likewise, the Mazda5 needs to be a recent model if it's to have the current 1.6 diesel that brings with it lower tax bills. So, try and track down a 2009 Citroen C4 Picasso with the 1.6 HDi diesel and the EGS automatic gearbox. That has a 140g/km CO₂ emissions figure, so you'll just scrape into the top end of Band B with a €280 tax bill.

How does that sound?

Hi Joe,

We really liked the Kia Sportage when it came out (here's our original Irish test drive) and though it's due a facelift next year it's still one of the most appealing small SUVs out there, not least because of its seven-year warranty. It also has a good 1.7-litre diesel engine now.

Anything else you need to know?

Expert answer

Hi Ian,

If nothing else, you need to adhere to manufacturer servicing schedules to ensure you don't invalidate your warranty. If you don't trust your local dealer then contact Opel directly, though these figures should be in your owner manual as well.

Besides all of that, we'd thoroughly recommend servicing modern diesel cars regularly, as the car makers often push the service intervals out to appeal to fleet buyers. Regular oil changes in particular are a very good idea.

Hope that helps

Hi Stephen,

Would you consider a Skoda Yeti? It's a similar size to the Juke but much more spacious, with a more sophisticated cabin and brilliant rear seats that can tip, fold and be removed altogether if you need extra load space. The boot on the front-drive diesel models should be plenty big enough to take a scooter or wheelchair too, and the DSG automatic gearbox is available. I presume you're already familiar with the work the Irish Wheelchair Association does with modifying cars for hand control, so that should be a simple enough process for you. A cracking car, the Yeti - brilliant to drive and very practical, and with a new model coming later this year, you should be able to argue yourself a decent deal on a new one.

Hi Alan,

By 2006 that 1.9 TDI engine was nearing the end of its life, and so had most if not all of its earlier issues (injector problems, air sensor failures) ironed out. As for the flywheel, yes there does seem to be an issue with it occasionally, but the way to tell is to listen to the engine, getting your head as close as safely possible to where the gearbox is located. If you hear a rattle, or feel an obvious vibration, it's probably the flywheel.

Hi Caroline,

That's pretty much the only one, to be honest. At least so far. The front-wheel drive version of the RX 450h has CO₂ emissions of 140g/km, which means you'll pay just €280 a year to tax it. Not bad for a car like that. The problem is that you'll never get the kind of fuel economy that Lexus quotes for it. Around 30mpg will probably be the best you'll achieve. 

Later this month though, Honda will launch a 1.6-litre diesel version of its CR-V. It's not quite as big as the Lexus but is really very spacious and has a massive boot. With Band A4 emissions (€200 a year) of 119g/km, a smooth chassis and impeccable build quality, it could be your best bet.

Hi Ian,

There are really only two options when it comes to S-Max engines and those are the 125hp 1.8 TDCi diesel and the 2.0-litre TDCi diesel in 140hp form. There was a 163hp version as well, but they're pretty thin on the ground and forget about the rarer than hen's molars 2.5-litre 212hp petrol version with the engine from the Focus ST; it was fantastic fun but nobody bought one as far as we can tell.

Now, originally both the 1.8- and 2.0-litre engines shared the same 164g/km CO₂ rating, which makes road tax a bit on the pricey side (€570 a year), but in 2010, Ford facelifted the S-Max, dropped the 1.8 TDCi and introduced an updated 2.0 diesel with emissions of 143g/km, making for a much more palatable €390 a year tax bill. So, that's the one we'd advise you go for and as long as you get either a Zetec or Titanium spec version, you'll get a reasonable amount of toys to keep you happy in the cabin.

Cracking car, the S-Max actually. Spacious but terrific to drive. Let us know how you get on.

Hi Myles,

With that length of a daily commute, I'd reckon that you should definitely go for diesel and back in 2008 there was actually a choice of Focus diesels, with the run-out 1.8 TDCi and the incoming 1.6 TDCi both available. Both are excellent choices, with the 1.8 possibly having an edge on overall reliability (it's an older and more proven design) but the 1.6 having the edge in terms of fuel economy and emissions. Find a well-cared for example with full service history (those diesel injection systems are complex and need looking after) and you won't go wrong.
