Hi Eddie,

You've not told us how old the cars are that you're looking at, nor whether they are petrol or diesel, but it's pretty much the same answer in both cases. They share the same basic six-cylinder, 3.0-litre engine, but in different states of tune. The 525 has less power and torque effectively. It usually has a different emissions rating too so come back to us with more details and we'll give you the full picture.

Note: this is not the case with the current BMW 525d and 530d. The former now uses a twin-turbocharged four-cylinder 2.0-litre engine, while the 530d sticks with the 3.0-litre unit.

Hope that helps in any case

Hi Fintan,

OK, well you’re kind of cutting across class boundaries there — a Focus and a Mondeo are really quite different cars, with the Focus being smaller, cheaper and arguably more fun to drive, and the Mondeo being more expensive, but bigger, comfier and more refined. That goes pretty much the same for the Opel Astra and Insignia, or the Volkswagen Golf or Passat. So the first thing you need to work out is what you want, and what you need, and whether or not you need the bigger car, or if something more compact will do.

Of the brands you’ve mentioned, the VWs will probably do the best in reliability terms, with Ford being the most enjoyable to drive, and Opel falling somewhere in the middle, but you should also be considering the likes of the Toyota Auris and Avensis (best for reliability), the Peugeot 308 and 508 (stylish, good to drive) and the Mazda3 and Mazda6 (reliable and both very good to drive).

Hi Caroline,

As discussed via email, the new Auris is more refined and a little more economical than the Mazda, as it has a 1.4-litre diesel engine to the Mazda's 1.6-litre unit.

However, as you've discovered, you're likely to get a better deal on trade-in with a Mazda dealer and that is likely to decide things.

By all means test drive both and shop around with different Toyota and Mazda dealers. By any normal measure both cars are incredibly fuel efficient.

Let us know how you get on.

Hi George,

We spoke to Volkswagen Ireland and it confirmed that yes, it is. Prices start at €23,175 for the Golf Plus Trendline 1.2 TSI 85 and rise to €29,355 for the Life 1.6 TDI 105 DSG version.

Engines are 1.2 TSI petrol in 85- and 105hp guises or 1.6 TDI diesel in 90- and 105hp outputs. DSG automatic available with both 105hp engines. Trim levels are Trendline or Life.

Hope that helps

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.

Expert answer

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.

If it was the older model you're interested in please come back to us.

Expert answer

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.

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.
