Hi Sinead,

Before tackling the diesel issue, the Nissan Qashqai is a fine car. It's a little bigger than the Golf and feels it because of the higher driving position and larger boot. In general it has proved to be a reliable car with only a few minor issues cropping up.

The 1.5 dCi diesel is a good choice of engine, though if you really do stick to Dublin and its environs it may be worth considering the cheaper 1.6-litre petrol instead. It's a shame Nissan doesn't currently have a smaller capacity turbocharged alternative, as that would be a great option. The diesel car will be more economical for sure.

Hope that helps.

Hi Cian,

We don't profess to be van experts, so we put this question to Gerry Murphy, a jury member on the Irish Van of the Year panel. His response is:

"The Volkswagen Transporter is a popular choice and owners are generally very loyal to the brand so repeat purchases are common place. Buying a used van is a little more complicated than buying a used car. As with any commercial vehicle, what the van was used for previously will tell you a lot about it. Did it tow a trailer? Was it used in the construction industry - often carrying heavy loads - or was it used to deliver flowers or light goods around a city?

A close look at the interior and cargo area for wear and tear will tell you how the van was treated. Also, vans that are owned by private members of the public are often better treated than vans that come from a fleet. As with any vehicle check if it has a service history. This is essential.

As for the Transporter, you don't say what year it is but there are things to look out for. Check that the area around the turbocharger is dry and not showing any signs of leakage. Also look under the vehicle from the rear and check that there are no signs of damage to the coil springs especially if the van pulled a trailer in its previous life."

Hope that helps

Hi Ann,

Our writer Kyle Fortune drove the new ML 250 CDI so I've passed the question to him for answering. This is what he said:

"The base 250 CDI engine in the ML is actually a 2.1-litre turbodiesel mated to a seven-speed automatic to best make use of the engine's torque and power spread. It works relatively well too, so long as you remember you're shifting quite a lot of bulk without masses of power. That said it's got a sizeable 500Nm of torque generated low in the rev range, so the ML 250 CDI is rapid enough in town traffic. It's only out of town - on a motorway slip road when you push it - that you'll perhaps be a bit underwhelmed by the performance. It's all about expectations though, and really, it's a credible performer.

As to the BMW? It's difficult to comment on a car that doesn't exist, but experience of BMW's small capacity turbodiesels does suggest that they typically over deliver on expectations - the 520d for example feels very rapid given its size and weight. How that will translate to the bigger, weightier X5 is questionable, though BMW is unlikely to release a product that's not at the top of its game. We've not heard anything about a 2.5d X5 (officially or not), but it's quite possible given the prevailing economic climate and the ever tightening quest for economy. Downsizing is common so it stands to reason that BMW might be considering it for the X5."

Hi Patrick,

On its own, the RAV4 2.0 D-4D is a fine car, with loads of power. It has plenty of low-down torque for towing too, though how heavy is your caravan? The manual Santa Fe has a higher towing capacity and it's a heavier car too, which will help in certain situations. Added to that, the Hyundai has more power and torque - (assuming you're talking about the newer 2.2-litre model) though obviously you pay for that with fuel consumption and tax.

Both cars have a good reputation for reliability though in fact it's the Toyota that has some history of issues - particularly with RAV4s used as tow cars. Apparently early versions (pre-2003) had transmission problems, though we'd hope the 2005 model is better.

Still, based on what you've said, we reckon the Santa Fe is the better bet in this instance, especially the newer model launched in 2006.

Let us know how you get on.

Hi Rory,

I don't have a strong opinion for or against the idea. I can see merit in the technology, but also major hurdles and potential issues. First, some good points:

• Potential to significantly reduce collisions caused by careless or distracted drivers
• Big gains in efficiency and fuel economy - on average
• Long-term could be used to transport people that cannot drive
• Could help ease congestion, especially on motorway networks
• Could eliminate drink-driving once and for all!

Some negatives:

• We all know that computer systems are far from infallible
• If something goes wrong, who is responsible? Legal minefield
• Would breed a whole generation that may never learn to drive for themselves
• I love driving and would hate for that choice to be taken away from us

We already have aspects of this technology in our cars right now, with things like Volvo's City Safe system (it can brake the car with full force if it detects a pedestrian in the car's path and the driver does not react) and Honda's Lane Keep Assist (where the car gently steers itself back on course if it thinks you're distracted) and it's likely they'll become more commonplace. Self-driving in really slow traffic may be next, though at all times a sober, responsible driver will have to be behind the wheel.

Fully autonomous cars are a long way off.

What are your thoughts?

Hi Justin,

You've not mentioned the age of the Pathfinder. If it's newer than the Volvo, then it's not a bad deal, though doesn't strike me as amazing when you look at the prices being asked for similar Volvos and Pathfinders.

With regards to what we think of the Pathfinder... It's a fine rugged, capable off-roader, but you may suffer from culture shock moving from your Volvo. The S80 is far more comfortable on the road and, loud engine aside, more refined in general. Obviously the Pathfinder can do serious off-roading and has much more space. The Volvo is probably better on fuel too.

In your position, I'd shop around a little more to see what you can get for your money and, if you don't need the towing capacity or off-road ability, consider something more road-biased.

Do come back to us if you need anything else.

Hi Deb,

There are loads of four-door city cars that would fit in that space that have ISOFIX, but the problem then is fitting a big travel system buggy into them! I myself have two kids so I understand the challenges...

Some good city cars to consider include the funky new SEAT Mii/Skoda Citigo/Volkswagen up! triplets and the Fiat Panda. They're as narrow as you get really.

Just so happens I have a Mii on test this week and our Quinny Buzz buggy folds in - with no space to spare of course.

Hope that helps.

The arguement for petrol is growing Brendan. While everyone is fixated on diesel the petrol engines are getting cleaner and will come back into fashion. When it comes to fuel economy the gap between petrol and diesel is getting closer and in a lot of cases there is little difference between the road tax.

The 1.4-litre petrol engine in the Passat is more than good enough. So if you want a Passat then you could go for it. There could and perhaps will be less value in the petrol model later on, but if you keep it long enough suddenly this won't become that much of an issue and since you go low mileage then you could keep it for 5 or more years.

Hi Derek,

Glad you like the site. Let's hope we can live up to your expectations! We got a little bit of extra information from you and you told us that you are trading in a 2000 Mazda 323 five-door and that your budget is around €30,000-€32,000, which is plenty to work with.

Given your criteria, and the fact that you mention the Audi A5, then I've had a look at some of those. You mention petrol models and with your low mileage then you could quite easily run a petrol car, but given the fact that you are concerned about residuals then the diesels in the A5 would make a better choice. There is a lovely 2.7-litre TDI A5 in the classifieds and this is under €30,000. It would be a smashing buy and the fact that it has quite high mileage doesn't really mattter in your case. The 2.7 TDI version would hold its value better than a 2.0T petrol. 

At the other end of things you mention the Mazda6 - an odd contrast to the Audi but still a nice car nonetheless. You are unlikely to find a petrol-powered Mazda6 because Mazda really hasn't sold any in the last few years in Ireland. Plus, it wouldn't be a good use of money because it would be hard to sell on again a few years down the line. The diesel version is so much better anyway these days and you could have a demo 2011 model for well under €30,000. It is a nice car, but to be honest we can find you something a little more interesting. 

How about a Jaguar XF 2.7 D Luxury? What a super car, for €33,000. This is a marvellous example and fully loaded with kit. Another outside bet would be a 2008 Lexus GS 450h. We found a low mileage one that would be great around town and it is super fast. 

After all that, this is the car I think would suit you best. It is petrol, a 320i, but it is a hard-top convertible and it looks awesome. I don't know if you are a BMW fan but this could be a brilliant buy for you. 

Come back to us if we've not hit the nail on the head.
