Hi Robert,

The estate (or 'Grand Megane' as Renault insisted on calling it) TomTom edition was announced in 2009 and introduced to the market in 2010. It was much better built and more reliable than the previous Megane, but there are still some weak points to keep an eye out for. Those include fragile fuel line clips, burned out coil packs on the 1.6 petrol, particulate filter problems on the 1.5 diesel, electrical problems especially with the windows and the heating system and premature clutch wear.

Hi Patrick,

If you mean the current model, then I’m afraid it’s a little too early for us to tell, as it hasn’t been around long enough yet for any major reliability issues to shake out and all cars would still be under warranty. We’d be surprised if it has suffered anything major, though – it seems very well built.

The older model is also very well built, but you need to check for sticking exterior door handles, trouble with the diesel particulate filter (DPF), faulty electronic handbrakes, dodgy stability control modules, leaky sunroofs and excessive front brake wear. If it has the DSG automatic gearbox, you also need to check and make sure that it has been properly serviced, and on time, because it’s a complex piece of equipment that needs careful looking after.

Hi Lorraine,

They're OK from the point of view of reliability (although the 1.5 diesel can suffer from blown turbos and you need to keep an eye on the electrical systems), but if they're the same price then go for the Laguna - it's a much more sophisticated and better-driving car than the Fluence.

Hi Mark,

If it’s the 2.2 180hp, then it’s 185g/km of CO₂, which is Band E and €750 a year. If it’s the standard 2.2 diesel then it’s 173g/km, which is, er, exactly the same – €750 a year.

Hi Aine,

It will depend on the spec and mileage, but €3,900 should be a good ballpark to start with.

Hi Ruairi,

The Auris stands out mostly because it will be the most reliable and also because it has the most interior space. That said, the 1.4 diesel isn't perfect and does develop oil pump issues so check to see if it's had any remedial work done.

Of the other two, the Megane is a solid and sensible choice and the 308 is roomy and very economical. Overall, I'd say the Toyota is the best bet though.

Hi Nigel,

The Duster has been on sale in Europe for more than a decade now and, for the most part, it has built up a decent reputation for reliability. Because it’s so basic, it lacks many of the more modern electronic systems that cause so many problems in more expensive models, which helps. The 1.5 dCi diesel is a sold engine, although you do need to keep an eye out for troubles with the turbo if it hasn’t been serviced properly.

Other things to think about are damage underneath the car from owners trying to drive further off road than the car was designed for. As long as you’re buying one with a full service history I wouldn’t have too many concerns.

Hi Cathal,

You are indeed entitled to a refund, but not immediately. Under the Sale of Goods and Supply Of Services Act, if a product is “not of merchantable quality” then you are entitled to a repair, replacement or a refund. It will be up to you and the dealer from whom you bought the car to discuss which of these will be the case, and most dealers will try at least to repair the car at first, as obviously that’s usually the most cost-effective route from their perspective.

You can demand a refund and nothing else, but I’d make sure you have a good solicitor on your side before doing that as technically if the dealer is offering you a repair then they are fulfilling their duties under the act.

Hi Tony,

How come the Prius wasn't used for a couple of years? That's the first question you'll be asked. If it's in good condition and still works fine, and you can show a current NCT, then there's no particular reason that a dealer wouldn't take it as a trade in, but you'll need to be honest and open about the history of the car. 

Expert answer

Hi Kieran,

Yes, turbocharged petrol engines do often have exhaust gas recirculation (EGR) systems and dual-mass flywheels, but they are far less likely to cause problems due to, respectively, the different exhaust gases and the torque characteristics of the engine. Added to which, petrol engines work at lower combustions pressures and with less vibration than diesel engines so there's a little less wear and tear to worry about.

No, turbocharged petrol engines don't have particulate filters as, for now, they're considered 'clean' enough not to need them. That will change in the coming years, however.

Finally, the low-down-power thing is simple physics. Most turbocharged petrol engines and their diesel counterparts are pretty close on top-end power numbers (generally grouping around the 110-120hp level), but the difference you're talking about is torque - turning force, that low-down lugging sensation. Some of that is down to turbo design and the fact that a heavier diesel engine can accept higher turbocharger pressures, but most is simply down to the fact that diesel burns from compression ignition, which generates more torque and makes the engine feel more muscular at lower rpm.
