Hi Des,

As with all Suzukis the Grand Vitara is impressively well bolted together and there are very few reports of any major reliability issues. The only recurrent problems seem to be glitches in the electrical system, but as long as the car you're looking at has a full service history, you should be OK. There are only two major downsides: the interior looks and feels pretty cheap and old-fashioned compared to some rivals, while the 1.9-litre diesel engine (which Suzuki actually bought in from Renault) can be very thirsty, as the Vitara is no lightweight.

Hi Noel,

I actually quite like the Mokka; it's good looking, has a pleasant interior and is quite good to drive. However, I'd hold off on buying one until the new 1.6-litre diesel engine comes on line. The current 1.7-litre is an ancient design, noisy and rattly and prone to stalling at low speeds. Avoid that and wait for the new engine if you can, or if you're only doing low mileage, consider the excellent 1.4-litre turbo petrol unit instead.

Hi Aisling,

No, it should be OK as long as you are absolutely on-the-ball when it comes to making sure that it has a full service history. The Tiguan is essentially a tall Golf, so all of the mechanical bits are pretty robust and well proven, but watch for some small niggles. The electronic handbrake (if fitted) has been known to fail. The rear door handles can stick open, but that should have been sorted under warranty and the air conditioning can fail, but that's usually just the dashboard switches and not the deeper mechanical bits of the system. Oh, and check carefully underneath for signs of off-roading damage - Tiguans aren't really designed for proper mud-plugging, but the four-wheel drive system sometimes fools people into thinking that they're Land Rovers...

Hi Darrell,

Generally speaking SsangYongs are very reliable (it's the upside of them being somewhat old-fashioned and mechanically simple), but the price you pay for that is them being really rather crude to drive and live with. Noise levels from the engine will be very high indeed, cabin quality will resemble that of a Toyota from the 1980s and the handling will be little short of terrible.

Hi Tina,

There's not a lot to choose between them in terms of overall pricing or cost of ownership, but we'd go for the 1.6 diesel simply because it suits the car better and the extra torque on offer makes it a more relaxing drive, especially on the motorway.

Hi Graham,

It depends which model you are referring to. Our records show the following:

- RAV4 2.0 VVT-i (petrol) automatic: 212g/km - Band F, €1,200 per annum

- RAV4 2.0 VVT-i (petrol) manual: 202g/km - Band F, €1,200 per annum

- RAV4 2.2 D-4D (diesel) manual: 173g/km - Band E, €750 per annum

Come back to us if it's something else and we'll look into it.

Hi Mark,

The more recent versions of the Renault Grand Scenic are at least reasonably reliable, and the commonly-seen 1.5-litre diesel engine is a sold enough old lump, and well proven in various Nissans and Renaults. The recurring nightmare is that of electrical problems. Renaults, older ones at any rate, just seem to eat through their cabling and wiring and everything from electric windows to engine management and injection problems can crop up. Buy very, very carefully if you're looking at  anything older than 2008.

Hi Ann,

Yeah, you might just scrape into a 2012 model in either car but to be fair, though rolling back to a 2011 or even a 2010 (assuming that condition and history are OK) isn't really going to be any hardship. As for the C4 Picasso, well it's a very, very different type of car altogether - a big, spacious family MPV rather than a low-slung sports saloon. They're nice and comfy, but won't be as well built as either of the German cars.

If it were our choice to make, we'd go with the Audi - comfy, decent to drive and reliable.

Hi Aoife,

We asked Toyota Ireland what it thought would be reasonable oil consumption, and though you haven't told us the age of your car it was suggested that a rate of a quarter litre of oil per 1,000 kilometres was normal. Toyota suggested that, if you suspect there is an issue, bring the car to a dealer and as for an oil consumption test to be carried out.

Hope that helps

Hi Des,

If you mean the new model, which was introduced in the summer of 2013, then it's generally excellent. Gorgeous to look at (well, we think so anyway) with a fantastic interior, lots of space and excellent economy from the familiar 1.6-litre diesel engine. Citroen's build quality has greatly improved over the past few years, so you shouldn't have any major reliability worries and it's an immensely comfortable car in which to do long journeys. Here's our Irish road test of the five-seat model.

If you're talking about the previous generation then there are a couple of points to keep an eye on. The 1.6 diesel has a habit of developing problems, usually with the turbo's exhaust gas recirculation (EGR) valve. It's a relatively easy fix but it can be pricey so shop around for quotes. Buy as recent a car as you can, as Citroen was constantly improving the build quality as the car developed. Avoid the automatic EGS gearbox - it's awful to drive with and can develop problems with the clutch. Check the cabin very carefully for loose or rattling trim and inspect the bumpers, especially the enormous one-piece front bumper, for any damage - they can be hugely expensive to repair.
