Hi John,

A lot will depend on the condition and service history, but it should be worth in the region of €9-10,000 — maybe €7-8,000 as a trade-in.

Hi Paul,

I’m tempted to say get another 520d — for the budget, they’re hard to beat. Well worth looking at an Audi A6 2.0 TDI as an alternative, though, and a Mercedes E 220d. Or a Jaguar XF if you’re feeling like a bigger change. Of course, what you could do is take that budget and spend it on a two-year-old Skoda Superb and get a fully-loaded version...

Hi Shane,

The manual version uses 8.4 litres/100km (33.6mpg) and the automatic 8.5 litres/100km (33.2mpg).

Hope that helps

Hi Paraic,

First and foremost is the running costs, but I guess they're on the same level as any large SUV-based commercial with an automatic gearbox - they're heavy on fuel and tyres, etc.

Other than that, while the Discovery 3 is proving to be more reliable than its predecessor, it's hardly the most dependable truck of its type. Some cars are perfect, but others have loads of issues, from the electrics to the air suspension and even to full engine failure.

Don't settle for anything less than a full service history and make sure you have the car checked out by someone that knows what they're looking at too.

Hope that helps

Hi Sandra,

Both are lovely, and if the prices are more or less the same, we’d go for the 5 Series as it’s bigger, comfier and slightly nicer to drive. Make utterly sure it comes with a full service history, though, and beware of issues with the infamous timing chain.

Hi Nabeel,

No, the S40 gearboxes were all pretty solid, both manual and automatic. If an S40 is going to develop problems, it’s usually with the turbo on the 1.6 diesel engine, or with the central locking or ignition system. There is a bit of a disadvantage in terms of fuel economy with buying an auto S40, but it’s not a huge gap, depending on how you drive.

Hi Tommy,

First up, gearboxes: a six-speed gearbox in a given car usually means it is officially more economical than it would be if it had a five-speed gearbox, but that really will depend on the type of roads it's driven on and the driver's own style. It's not correct to say that a six-speed Renault, for example, is automatically more economical than a five-speed Ford though, as there are many more factors to consider. Best to look at the official combined consumption figures as a gauge - even though they're not usually achievable in the real world they are a good measure of one car against another.

A quick search on Carzone.ie reveals that your budget may get you into a 2009 Ford Focus 1.6 TDCi. There are plenty of different trim levels and 90- or 110hp derivatives available so take a close look at the specifications, history and mileage. Most of those are now in Band A4 with emissions of less than 120g/km and fuel consumption as low as 4.3 litres/100km (65.7mpg).

In terms of Golfs, it looks like you'd be lucky to get a 2008 version (the old one) for that same money, which means it'd have to be a 1.9- or 2.0-litre TDI engine. These cost more to tax (especially if you go pre-2008) and are a little less econonomical than the Focus above.

There don't seem to be many Renault Méganes fitting your description and budget, though a look elsewhere reveals that you may find a 2010 version at this price powered by the 1.5-litre dCi engine. This came in 86- and 110hp guises. The former is virtually as economical as the Focus and the latter only uses a little more fuel.

Finally, the Citroen C4: in terms of economy, the 2008 1.6 HDi 92hp engine is up there with the Focus etc, though there are more powerful versions available too.

In summary, if fuel economy is your priority then it's probably best to stay away from the older Golf, with its larger engine. The others are all very close and so it comes down to personal preference. We'd go for the Focus, not least because of the much wider choice of examples on the used market.

Hi Samm,

That’s a bit of a tight budget, so I think the best thing is to find something Japanese. Either a Honda Jazz or a Nissan Micra auto, from circa 2007, should do the trick and both are hugely reliable. Just make sure you buy one with a full service history.

Hi Gerry,

I'm afraid we've not driven the X3 sDrive. For those not in the know, that's the rear-wheel drive version of the BMW. It's offered in Ireland in '18d' format only, which means a 143hp 2.0-litre turbodiesel engine. It comes in manual and automatic guises and in SE or M Sport trim levels with on-the-road prices starting from €43,690.

Non-quattro Audi Q5s are powered by a 143hp 2.0-litre turbodiesel engine as well. While there are more trim levels offered (base, SE and S Line) this car can not be specified with an automatic transmission. On-the-road prices start from €41,760.

For the record, with a manual gearbox, both cars are in Band B2 for tax purposes though the X3 uses marginally less fuel on the combined consumption cycle (5.1- vs. 5.4 litres/100km) and it's a second quicker accelerating to 100km/h at 9.9 seconds.

Hope that helps in some way

Hi Joe,

This Range Rover is one of the better built cars from Land Rover in a while actually. Some early examples had issues with the automatic gearbox and water leaks, though these should have been well cured by 2005. Electrics and the sophisticated suspension system seem to be the biggest worries, and of course they're expensive to repair.

If you're serious about one, insist on a full, detailed service history, and invest in a professional inspection too.

Hope that helps.
