Hi Evelyn,

Actually, the Hyundai ix20 might be just the thing you're looking for. It's smaller and cheaper to run than a Golf, and that 1.4 diesel engine is very economical, and will actually prove more powerful to drive than the Golf. Others worth considering are the Citroen C3 Picasso or Ford B-Max, both of which can be had with either petrol or diesel power. Try a 1.0-litre turbo petrol B-Max actually - great fun to drive and you won't believe the power and performance Ford can get from its new downsized 1.0-litre engine.

Hi Jason,

A really good car, that 2002-2007 Corolla. 'Quiet' looking inside and out it may be but the strength of the engineering underneath is palpable. The sheer quality of the cabin was vastly ahead of any other contemporary rival (even the supposedly tank-like Volkswagen Golf Mk IV) and the primary engine, a 1.4 petrol VVT-i unit, out punched most rivals by about 15- to 20hp while also being more economical.

It's also surprisingly good to drive. It'll never set your shoes on fire, so to speak, but in a former life I thrashed one around Mondello Park and it showed a depth of competence in the chassis that would surprise most Corolla drivers. 

On the reliability front, there's little or nothing to worry about. The only recurring complaints seem to be rear lights that allow condensation to build up inside and annoyingly squeaky brakes.

Hi Ruadhan,

That, I'm afraid, is a question with too many variable answers. Second-hand vehicle values are like stock market values - they go up and down and often rather unpredictably. There are a few rules of thumb, though...

1. It's got to be diesel. Yes, we (and others) have tried to educate the motoring populace that diesel power doesn't automatically mean better economy or lower running costs, but right now the market is diesel-crazy and if it doesn't sip from the black pump, it's not going to hold on to its value.

2. The lowest depreciating cars are, obviously, the most popular models. So the likes of the Ford Focus, Volkswagen Golf, Nissan Qashqai, Hyundai Santa Fe, BMW 3 Series, Audi A4 and so on will always hold on to their value the best. Check the list of the top-ten best-selling cars on the market - these are your depreciation heroes.

3. What about depreciation villains? Anything that the market doesn't trust, really. Estates tend to fare especially poorly, anything with a French badge is suspect and if it's Italian, forget it. You'll lose your shirt on any of these.

4. Spec is king. You can have the most in-demand car going but if it's painted bright yellow and has green seats, you're never going to shift it. So, to keep depreciation at bay, stick with dark metallics and subtle interior tones. Pale cabin colours tend to fare less well when it comes to wear and tear, so the market prefers blacks and greys on the inside too. If it's an executive car, it has to have an automatic gearbox. Anything with factory-fit air conditioning and Bluetooth telephony is looking good, leather is always helpful but other expensive toys don't always help a car hang on to its value.

Hope that's all of interest

Hi Blaithin,

In my personal experience the most efficient car I've ever driven was the Volkswagen Golf BlueMotion - it easily averages better than 60mpg in everyday driving and I'm not the most economical of drivers. €20k should get you a nicely specced 2010 or 2011 model.

How does that sound?

Hi Bernard,

Oddly, they're identical. According to the official figures both the 2001 1.8 turbo 150hp Golf GTI and the 2006 Octavia RS 1.8 turbo 180hp return 35.3mpg on the combined cycle.

Hi Brendan,

Good choices, all of those, if you're looking for a more affordable 3 Series alternative. The new-shape Mazda3 (the one that's only just been launched) seem to be especially excellent, and with Mazda's reliability you won't be spending too much on repairs or maintenance down the line. The Golf is always a safe bet too, although if you're used to the saloon shape it may be worth having a look at the little-seen Jetta - an underrated gem, that car. Or, alternatively, you could try the Audi A3 Saloon, which I reckon is the best compact sports saloon around at the moment.

See how you get on and let us know which one you go for.

Hi John,

Yup, a small diesel sounds like it should be ideal for you. Depending on what kind or size of car you need I'd recommend either a MINI Cooper D 1.6 (small and sporty), Opel Astra 1.3 CDTi (slower, but more spacious), Toyota Auris 1.4 D-4D (similar to Opel but probably more reliable) or that old favourite the Volkswagen Golf 1.6 TDI BlueMotion (ultra economical). Or, if you need more space how about a Skoda Octavia Combi estate 1.6 TDI or a Citroen C4 Picasso 1.6 HDi?

Hi Patrick,

We haven’t been able to find any evidence of a Volkswagen-instigated sensor replacement programme, but it seems that there are two possible issues here. First, some of the problems may just be brake and tyre dust covering the sensor and a proper clean might do the trick. Secondly, it could be that the wheel-hub is failing, and that is what is triggering the sensor issue so we’d advise getting the car inspected properly to see if that’s the case.

Hi Phil,

"Most economical" is something of a loaded question as it's really much more dependant on your style of driving and the routes you use as much as anything else. 

What I can tell you though is the car in that class I've been able, consistently, to get the best economy from. It's a Golf. To be precise, it's the Mk VI Volkswagen Golf 1.6 TDI BlueMotion. Test driving it on a warm, sunny day with the air conditioning going and not paying a huge amount of attention to being economical, I managed an average of 65mpg. I haven't yet driven the latest Mk VII Golf BlueMotion but would suspect you could do even better again, possibly as good as 70mpg.

Hi Donagh,

All of the cars you've listed there will be both a lot more reliable and much more economical than your 407, but potentially your best bet is to stay within the Peugeot dealer network where you'll most likely get the best deal on your trade-in. The new 308 is looking pretty impressive, comes with a five-year warranty and Peugeot's build quality has come on a long way since the 407...
