Hi Garath,

Yes, absolutely. True, diesel values are softening a little with all the adverse publicity, but the 520d is a car that’s going to retain its allure for a while yet, and in the meantime it’s frugal, refined and brilliant to drive. If you’re a low-mileage driver, it’s very definitely worth considering either a petrol 520i or a plugin-hybrid 530e, but for long-distance driving the 520d is still king.

Hi Daniel,

Sorry to hear about the Scirocco - that 2.0 TDI version is great.

A quick browse of Carzone.ie with your budget and needs in mind brought up a few interesting options:

- Audi A3 2.0 TDI 140 - in Sport or S Line guises for maximum style - loads around
- BMW 118d M Sport - quite rare, but great to drive
- BMW 320d Coupé - you'd have to go pre-2008 with your budget, but current style at least
- Honda Civic Type S - 2.2 diesel is great and post-2008 is taxed according to emissions
- MINI Cooper D - loads around in all different colours at your budget

I've picked out the cars I reckon you'll like and I've left out things like the Volkswagen Golf and regular Ford Focus (among others).

What do you think?

Come back to us and let us know if we're on the right track.

Hi Moss,

We've scoured Carzone.ie with your budget and needs in mind. There are loads of diesel SUVs available at that price, though we've shortlisted the ones here we reckon would do the job for you:

- BMW X3 - economical, though you're looking at an older one at this price

- Honda CR-V - great option if you can find a good one

- Hyundai Tucson - plenty around, though not as 'nice' as premium models

- Mitsubishi Outlander - with Volkswagen's 2.0 TDI engine - good bet

- Nissan Qashqai - great all-rounder, though possibly not quite SUV-like for your tastes

- Peugeot 4008 - stylish, good diesel engine, should be able to afford post-2008 car

- Toyota RAV4 - safe bet, though will be pre-2008 on your budget

If you'd like us to help narrow down your search feel free to come back to us.

Hi Lisa,

That car is taxed according to its engine size, which is 2,184cc. Changes for the 2013 Budget mean road tax for this model has increased from €885 to €951 per year.

Hope that helps

Hi Mairead,

That’s the 1.6 diesel that’s in almost everything; from Citroens and Peugeots to MINIs, Fords, Volvos and Mazdas. As such, it’s a pretty reliable engine, as long as it’s been properly serviced and fed a regular diet of high-grade synthetic oil. Keep an eye on the fragile water pumps and exhaust gas recirculation valves, though.

As for the rest of the car, tread carefully. That was the last Citroen to come with the legendary Hydragas suspension system as standard, and while that’s terrific from a point of view of comfort, it is a complex and often fragile system. Ditto the C5’s complex electrical system. Make sure it has a full and complete service history and, if there are any gaps or if the overall condition is anything less than excellent, walk away.

Hi Paddy,

The Honda CR-V has a great reputation for reliability in general, but a surprising number of things go wrong. I'm going to assume you mean the 2.2-litre CDTi diesel version. Here's what we know about:

- Earth connection for ABS can cause various error codes, but is easily fixed.

- The ABS hydraulic modulator itself can deteriorate, meaning poor braking. That's expensive to fix.

- Issues with the air conditioning are usually to do with a faulty (and easy to replace) relay.

- The dual-mass flywheel can break up and cause vibration.

- The EGR valve sticks due to carbon build-up, causing poor running, stalling and intermittent power loss.

Along with all those things to look out for, there are loads of creaks and noises the car makes, but all can be fixed at relatively low cost.

Hi Ollie,

Generally speaking, you should be OK, as that 30-min run each day should be enough to keep a DPF hot enough to clean it out, but that’s if and only if that 30 mins is all run at high-ish speeds, say above 80km/h most of the time and in a lower gear. If you’re spending a lot of time in stop-start traffic, I think a petrol option might still be the better one. Mazda’s 2.0-litre petrol engine can be a bit thirsty, but the 1.4 TSI option in the Passat and A4 is a very frugal engine, and still has peppy performance.

Hi James,

As discussed via email:

That generation Audi A6 is in general a reliable car, but not fault-free. Some owners have had no problems, while others have been plagued. The Multitronic transmission is not renowned for being the most trouble-free, though units made pre-2006 have the most problems. Also, the gearbox's fluid should be changed at 55,000 and 115,000 kilometres (or 35,000 and 75,000 miles) so the car you're looking at should have had two changes by now. Check that it has and then look in detail at how the gearbox works. Does the 'PRNDS' indicator on the dash flash? Is there hesitation? Is it easy to get reverse?

No matter what turbodiesel car you look at you'll hear of turbo problems from some owners. Most of the time it's likely to be due to poor oil maintenance. So check the car's service history in terms of oil changes and that the oil level itself is right. They do use a bit of oil.

While you're checking out the car in detail, make sure the air conditioning can produce freezing air in just a few minutes, as these have been known to fail.

I'm probably making this sound worse than it is! I'd buy an A6 for myself - it's a good car - you just need to know what you're looking for and not get caught out by one of the few badly maintained examples out there.

Let us know how you get on.

Hi Sean,

I don't think you're asking for too much actually, so long as you don't mind a car that's a few years old. There's plenty of choice at that price point. You've not told us how big a car you need or how far you drive each year so we're keeping an open mind there, but only shortlisting diesel saloons and hatchbacks. Options include:

- Ford Fiesta 1.4 TDCi

- Ford Focus 1.8 TDCi

- Ford Mondeo 2.0 TDCi

- Nissan Note 1.5 dCi

- Peugeot 407 1.6 HDi (only if it has a full service history)

- Skoda Octavia 1.9 TDI
