Hi Tara,

If you mean the last-generation Volvo XC70, introduced in 2013, with the D5 diesel engine, then that has CO₂ emissions of 153g/km, so that means Band C tax, and €390 per year.

Hi John,

That's kinda a 'how long is a piece of string?' question, as no two engines are created equally. I mean, every different 1.6-litre diesel engine has a different realistic life span. And while it's reasonable to presume that a diesel engine is designed to be driven over higher mileage, I don't believe that manufacturers aim for 'worse' durability for their smaller petrol engines.

Hi Robert,

The M50d has more peak power and torque and is quicker accelerating than the hybrid model, no question. However, the six-cylinder diesel engine is a lot louder and less smooth than the straight-six in the xDrive45e model and obviously, when the hybrid is running in electric mode it is far far quieter again. As you say, the PHEV comes with compromises, and may not be as economical over a long journey where the battery cannot be charged from an external source.

Hi Kevin,

You’re charged the higher rate because your car is a 2007 registration — so it was registered before the switchover to the CO₂-based tax system, which kicked in in January of 2008.

Hi Martin,

The price looks reasonable — about in the middle of the road for a 2015 A4, so the true value will depend on the car’s specification and its overall condition. A figure of 72,000 is a very reasonable mileage if it’s in miles (and if it is in miles check to see if the car was imported from the UK — that’s not necessarily a problem but you’d want to be a little more wary about its history if it is an import) and exceptionally low if it’s in kilometres. If it is 72,000 kilometres, rather than miles, I’d actually be slightly suspicious of that figure, as it may have had the clock turned back.

Audis are well-made, and generally very reliable and that 2.0-litre TDI engine is solid, but make sure that it’s had its software recalibrated to reduce its pollutants (the changes that were mandated after the diesel scandal became public) and make sure that it has a full and complete service history — these are complex cars that need looking after, so if there are any gaps in the service record, I’d walk away; there are plenty of other A4s out there.

Hi Roger,

That is a significant change, leading us to suspect something may have been altered during the belt change. The tensioner could be too tight, for example, or the fuel pump timing might be out. Well worth bringing the car back to the garage and asking them to check all of this before it potentially causes problems with the engine.

Hi Michelle,

Well, a Porsche Macan or Maserati Levante would certainly be fun choices, but possibly not the best from the point of view of your parents… One potentially very good option could be the Volvo XC60 T8 Polestar — a plug-in hybrid with serious performance and excellent handing, but loads of space in the back and really comfy seats. Audi’s new SQ5 diesel is another good choice (really comfy and plenty roomy), as would be the mighty V8 diesel Audi SQ7. To be honest, though, if you want to spend big on a luxurious SUV that’s also fun to drive, it’s pretty hard to look past a Range Rover...

Hi Barry,

Actually, the X-Type diesel was beset with a long list of issues. Most of them are relatively inexpensive to fix, but there are loads of known electrical problems and generally poor build quality as well. A 2009 car would at least, but late in the model's life cycle, so it may be better than early examples, but it's not a car that we'd highly recommend in terms of reliability and cost of maintenance.

Hi Kris,

The problem is that Irish insurers are a bit blunt-force when it comes to deciding their rates, and generally speaking (and completely erroneously) they simply tend to go by engine size. So even though there are plenty of older 1.9-2.0-litre diesel engines with similar power outputs to a more modern 1.6, they’ll probably quote you more just because it’s a bigger engine. Stupid, but then that pretty much sums up the insurance industry in Ireland. All I can suggest is either biting the bullet and getting a 1.6 that maybe you’re not as keen on, or finding a really good local broker who can help you track down quotes that us mere mortals can’t find.

Hi Ed,

That is an answer that will vary massively depending on which model of car you’re talking about. There are some Hyundai i30s and Kia Ceeds from around that era that came with a 1.4 diesel engine that would be hugely economical. You might be able to track down some Peugeot or Citroen models (a 2008 would be a good choice) with a 1.4 HDi diesel engine that’s good on juice, too. There’s also the Toyota Corolla or Auris D-4D, or if you don’t fancy diesel, the same cars with the 1.33-litre VVTi petrol engine, which was not too thirsty.
