Hi Dawn,

Going on personal experience, I'd say that the C4 Picasso would be the most economical of the bunch. All of them should be able to get between 45-50mpg, and I'd say the C4 should just nudge above 50mpg. That said, you have to remember that what dictates fuel economy more than the car is your driving style. Practice driving with light throttle openings, anticipating further ahead and always using gentle control inputs and you should be able to get that economy figure improved. Also, take any excess weight out of the car, make sure the engine is serviced regularly and the oil changed often and get a good set of low-rolling resistance tyres, and keep them at the right pressure. It all helps.

Hi Breda,

Well, on the one hand, both the Aygo and the Auris are very well built and reliable so both will minimise any potential for expensive maintenance costs, and both are very frugal and economical, so either would be a fine choice. The Auris might be a bit more of a painless switch if you've been used to a Golf, as it's similar in size and comfort levels.

But, as you say that your journeys have decreased in length, switching cars may not actually save you any money. Changing cars is usually more expensive than maintaining and running an older car, and you need to sit down and do your sums very, very carefully. Work out what the actual cost of change is for you (the price of either car you are considering minus the trade-in value of your Golf, but including the cost of finance) and balance that against the cost of continuing to run and fuel your existing car, factoring in some cash for a good service and a new set of tyres (often the best way to improve your fuel economy).

Hi Breda,

Yes, very, partially because they're Toyotas and partially because they're very simple and basic inside, so there are fewer things to go wrong.

Hi Paula,

Yes, very, very reliable. But also, I'm afraid, very, very boring. Still, sometimes it's the dullest cars that give the fewest problems...

Hi there,

The Meriva's pretty robust but there are a few reported problems. Most seem to do with the interior, which is not made of the highest quality plastics, and which develops a lot of creaks and groans over the years of use. Not much can be done about that, unfortunately. A more serious issue is to do with the steering. Power steering pumps can fail and it seems to be a recognised issue. There was a recall but not all cars, or indeed the entire problem, may have been fixed. Also watch for faulty timing chains on the 1.4 petrol.

Hi Ian,

Right, the bad news is that the Yaris isn't going to be worth all that much at this stage. I'd say if you get €1,000 for it, either cash or as a trade in, you'll be doing well. The good news is that gives you a €4,000 budget and that puts an awful lot of really good cars well within your reach.

Now, funny story. When we had our first boy, he was born in February. That Christmas, I borrowed a Land Rover Discovery to bring us all down to my wife's parents in Waterford. And thanks to all the luggage, buggy, travel cot, bath etc. etc. etc. I couldn't see out of the back of the damned car for a whole week. That's a long winded way of saying you need to maximise your space.

So how about a Citroen Berlingo? €4,000 should get you into a 2005 1.4 petrol model and there's so much space in the back that all that baby gear will fit easily. Don't fancy a van with windows? Then how about a compact estate? There are some nice Chevrolet Lacettis around - not the most exciting car in the world but reliable, comfy, well-equipped and spacious. Your budget should get you into a 2006 or 2007 model. Or, if that's a bit too left field, what about a MkII Ford Focus estate? We found a 2005 1.6 diesel with air conditioning that's in your budget.

Best of luck with the car hunt and the baby!

Hi Gary,

Automatic small cars are generally a bit hard to come by in Ireland, but I suggest a MINI One or First. Unlike some other small cars, the MINI's auto box is a sophisticated ZF unit and it's as much fun to drive as the manual. €5-7,000 picks you up a good one.

Hi Cindy,

I would go for either the Skoda or the Opel. The Skoda 1.9 TDI is very economical (50mpg should be pretty easy) and Skodas are well built and reliable. 

The only downside is that if it's pre-2008, it'll have a high rate of tax. That's something that the Opel with the 1.3 CDTi engine avoids, and it's still very economical, albeit slightly less so as you'll have to work the smaller engine a bit harder to keep up with the flow of traffic.

Hi David,

If the 2005 one has been better looked after, then go for that one. Condition is always far more important than age or mileage, and given that there’s no mechanical difference between the two cars, you won’t benefit from the newer model if it’s been less well cared for.

Hi Cormac,

It will depend on the year and model you’re talking about, but if you mean the 2008 Audi A6 update, which was the first model with the TDIe engine, then it’s basically lightly tweaked for economy and emissions, but those will be nothing to write home about compared to more modern cars. The TDIe could manage 53mpg and 139g/km, but that was with the 140hp engine, so it’s a touch under-powered in the A6. You could be better off going for a more powerful 170hp version, which will have slightly higher emissions, but which will probably do better in economy terms in real-world driving - and far more satisfying to drive.
