Hi Mick,

Well, given the list of priorities you’ve given me, either the Octavia or the i40 would seem ideal, although it’s the Hyundai that will hold on to its warranty longer, as it has a five-year warranty compared to the Skoda’s three-year one. The Skoda is by a very slim margin the nicer of the two to drive though, so you’ll need to bear that in mind. That said, the i40 is more refined overall (not to mention being a bigger car, with more space in inside), so it’s really a matter of deciding which of your priorities gets top billing.

Hi Chris,

You’re going to need something comfortable as well, doing that kind of mileage, so I’d suggest a MINI One D. There are a few around at your budget,  they’re exceptionally frugal, have good seats and are fun to drive into the bargain.

Hi Martin,

There are a couple of things to check - that engine needs a lower auxiliary belt change at around 120,000km so make sure that's been done. You need to be watchful for the diesel particulate filter clogging up and the return pipes for the fuel injectors can leak, so if there's a strong smell of diesel when you lift the bonnet, those will need replacing.

Hi Carl,

Yes, theoretically you can run any diesel car on bio-diesel, but you need to be careful with where you're sourcing your fuel from - low quality bio-diesel can clog your injectors up.

Hi Lurdes,

OK, lots to deal with here. Let’s go through it piece by piece. Theoretically, you will always get better value buying second hand than buying new. 'Buy at three, sell at five' (years old) is the rule of thumb to maximise your value and minimise your exposure to depreciation. But, you’ve been burned in the past by unreliable cars (been there, I feel your pain) so I would say that buying new is actually the best thing for you this time around, especially as you want to hold on to the car for an extended period.

Of the two cars you’ve mentioned, the Toyota Verso should be the most reliable. Nothing much wrong with the Ford, but if reliability is your priority then always buy Japanese. Happily, a manual 1.6 diesel Verso seven-seater is just inside your budget, at €29,100 and there is currently a €3,000 trade-in offer on that model, which means you’ll get a lot more for your old Scenic than you would if you traded it in normally.

There is only one hybrid people carrier so far, and that’s the Toyota Prius+, but to be honest, we couldn’t recommend it. For a start, a new one will bust through your €30k budget barrier, but beyond that it’s a disappointing car – far too thirsty unless all of your mileage is done in town at low speeds. The Verso is a far more versatile car.

Hi Jenny,

The Montana will be cheaper to buy of course, and I'd say overall reliability should be roughly similar. Tax is exactly the same if you're taxing them as commercial, but it gets a lot more complicated if you're taxing them as a private vehicle. Lots of hoops to jump through.

Hi Linda,

€6k is at the bottom end of 2009 Avensis trade in values and your Toyota dealer is possibly boosting your trade in a bit (€10k is definitely top end) to keep you in the family.

I think with 15,000km annual mileage you definitely don't need a diesel - you'll really struggle to make back the extra purchase cost in fuel savings and if you're not doing lots of long journeys you could run into problems with the particulate filter. The Audi wouldn't be expensive to run at all - they're reliable and frugal, but the servicing would probably be slightly pricier than for a Toyota.

As for the Auris Hybrid, I think it sounds like it might be just about right for you, especially as most of your mileage is around town and that's where it works best. You may find it hard to get the best economy out of it on that long run to West Cork, but the rest of the time it should be about right, and super-reliable too.

An ex-demo is always a good idea as you'll get it cheap with minimal mileage, but there are fewer of them around these days.

Hi Sebastian,

OK, you have a few choices here. I’d say with that mileage you’re on the cusp of needing to buy a diesel to maximise your fuel economy, but your budget is a bit tight for most diesel saloons of that age. So, how about a BMW 318i? It’s petrol but the good news is that it’s quite economical (you should get 40mpg easily enough) and more reliable than the diesel 3 Series. Or you could try a Honda Civic IMA Hybrid saloon. There are quite a few of those around in your price range and if most of your miles are done in town, it would be ideal.

Hi David,

Yes, they are different, but it’s not a simple difference. Basically, the ‘classical’ Audi quattro system uses a centre differential, supplied by Torsen, to deliver engine torque to both the front and rear wheels. The system has been hugely updated and altered over the years, both to improve efficiency and to allow for more torque to be sent to the rear wheels (the current version can send as much as 85 per cent of the engine’s power to the back).

The Volkswagen 4Motion system (which is also used on four-wheel drive Skoda models) is a simpler and lighter Haldex system that uses a differential and a series of clutches to send power to the rear wheels. It can disable power to the rears in order to reduce mechanical losses, friction and therefore improve fuel economy. This system has become markedly more sophisticated over the years, but it’s still primarily a front-wheel drive layout that can send power to the rear, while the Audi quattro system is a classic all-wheel drive setup that is always powering all four wheels.

Now, there’s a catch. Some Audi models, mostly the A3, Q3 and A1, use a modified version of the Haldex 4Motion setup, although it’s still badged as a quattro. And there’s a new 'quattro ultra' system coming shortly, which Audi says gives the benefit of all-wheel drive, but with less drag and better fuel economy.

So basically, yes, they are different, but the overall effect – extra traction in poor conditions – is more or less the same. A really keen and sensitive driver will be able to tell the difference between the two in terms of feel and handling, but for the rest of us mortals, they’re effectively the same.

Hi Cyril,

There are a few advertised ‘trick' fuel additives such as STP or Dipetane that promise to reduce the emissions from the engine, but these are at best unproven and at worst utter snake oil. Your best bet is simply to get the car thoroughly serviced and tuned up and make sure it’s running on high-quality petrol or diesel bought from a reputable source.
