Hi Frances,

If you mean a 320d diesel then yes, it's excellent. You should expect to get at least 45mpg in daily driving, a little more if you're careful.

If it's a petrol 318i or 320i then it'll be a little more thirsty but 35mpg on average should still be do-able.

Hi Caroline,

If you're not doing mega-miles, then I'd say go for the C-Class. Assuming all being equal, it's a much nicer car than the CLA, which, although gorgeous, is a bit on the cramped side and not all that brilliant to drive. The C-Class is really smooth and comfy though, and much, much roomier inside.

Hi Chris,

We put that question to Peugeot Ireland and the answer is simply no. It is not economically viable to make that change as the cost of the new parts and the work involved would be huge.

Hi Lorraine,

It depends on the condition and history. If one has a full service history, has obviously been cared for and is in great condition - and the other isn't - go for the one in better nick. That overrides any question about diesel versus petrol. 

However, assuming the two cars are in similar condition and both have decent histories, petrol versus diesel comes down to mileage. If you're doing more than 15,000- to 20,000km per year, then you need to be thinking about diesel. Below that threshold petrol is the better option, unless of course that low mileage is all at high speed on the motorway.

Hope that helps

Hi Enda,

I'd tread carefully here. If you don't like the semi-auto box on the Citroen then just let it go - it's not going to get any better and it'll bug you for the rest of your time with the car. 

As for the Renault, I'm just not confident predicting reliability. Generally, Renaults are now a lot better built than they used to be, but long-term they can still be a bit shaky. Also, the reason it's a high-spec 2010 model for such a small price is because Renaults depreciate faster than snow in summer. 

So, I think you might need to shop around a bit and buy something on the basis of reliability and condition rather than year. Have a look at the likes of a Ford S-Max, Toyota Verso, Volkswagen Touran or, if six seats rather than seven will do the trick, a Honda FR-V. You might need to go back to a 2008 or 2009 model to get one within budget, but buy with a full service history and keep the maintenance up and any of those should give you long and hopefully reliable service.

Last, but not least, Shane, our Editor, is in the same position as you right now and he has homed in on the Mazda5, which has an exceptional reliability record.

Hi Jonathan,

The Peugeot Expert 1.6 HDi diesel engine produces 90hp at 4,000rpm and 180Nm of torque at 1,500rpm.

It's also available with a 128hp 2.0-litre HDi option.

Hi Martin,

There are a few, actually. Volvo sells the V60 D5 Twin Engine here in Ireland, which is a plug-in diesel-electric hybrid, while Citroen sells the DS 5 Airdream Hybrid4 200. Peugeot used to sell the 3008 HYbrid4 too, but it doesn't appear to be on the price list now, while Mercedes-Benz has had diesel-electric hybrid tech for a few years.

In fairness, we don't expect them to get any more plentiful or popular. Hybrid technology is expensive to produce and diesel technology is more expensive than petrol, so putting two expensive sets of components together inevitably means a high purchase price, even if the emissions are low and the VRT is kept in check.

Hi Brian,

To be fair to Volkswagen, there's not a lot it can do. The problem is that car thieves are becoming far more sophisticated and are using some very clever boxes of electronic tricks that can break down a car's security systems in minutes, and make it think that the proper key and immobiliser is being used. There's not a lot can be done about it at the moment and in fact police both here and the UK are now advising drivers (not just drivers of Golfs, but of any car) to start using the old-fashioned crime prevention techniques - steering wheel and gearshift locks and driveway posts.

Hi Tom,

There's no doubt that the 1.6-litre petrol engine would fit in the Laguna's engine bay, but it could be a world of pain getting everything to work, from the fuel system to the electronics and sensors. We wouldn't recommend such a project.

Hi John,

The 2006 model is taxed according to engine size, and it fits into the '1,901- to 2,000cc' band, which costs €710 per year.
