Hi Valerie,

Nope, they're excellent. Mazda's reputation for reliability is well earned and the 3 is a really nice car to drive. They're a little plain on the inside, but they're certainly hard-wearing so if you're a family motorist that should reassure you. The only problem to report is that some early models suffered from turbo failure, but it seems to have been an isolated problem. You will have to put up with a little more road roar and tyre noise than you might expect, though.

Go drive one for yourself to see what you think and let us know.

Hi Tanya,

Actually, both cars have exactly the same engine - BMW's long-serving 3.0-litre straight-six diesel. The first generation X5 is little short of excellent, with terrific handling and a gorgeous, comfortable cabin. Reliability isn't the best though. The engines have occasional problems with fuel injectors and developing cracks in the inlet manifold, while steering and suspension are also prone to damage and wear. X5s are also notorious for chewing through tyres at a ferocious rate. The engine's air mass sensor can also fail, leading to poor acceleration although you'll spot that easily enough on a test drive.

Basically, it's worth getting any potential purchase checked over by the AA for any faults, and just ignore anything that doesn't come with a full service history. Oh, and it's better to go for the 2004 one - that should have the newer six-speed automatic gearbox (ignore manuals - they'll be worth much less come trade-in time) that improves fuel economy to just over 30mpg.

Hi Paul,

The turbos go so beware of blue or black smoke from the exhaust, and check the convertible hood for any signs of wear and tear. If it's leaking (damp carpets are the giveaway) then replacement parts and repairs can be very expensive. Check too for uneven tyre wear - it can just be that the previous owner has kerbed the wheels but it can also be an indication that the car has damage to its driveshafts.

Hi Rowland,

OK, there are a lot of parameters to go with here, but the basics are that you need a car that's cheap to buy (so it can't, sadly be too new), has affordable running costs and won't break down every time it rains. I reckon that gives you a choice of three or four key models: Honda Civic, Toyota Corolla or Auris, Kia cee'd or Hyundai i30.

Have a shop around and you should be able to find several of those all well within your purchase price range, while they all have efficient engines and excellent reliability records. In the case of the Kia and the Hyundai, they also have lengthy warranties, which, even if there's none left on the one you buy, at least means that they're more likely to have been looked after. My personal choice would be the Honda. Track down a nice 1.4 petrol Civic and I don't think you'll look back.

Hi Joe,

The last-generation S60 got a bit unfairly hit by various Irish tax regimes (it never had an engine under 2.0 litres for instance), but it's actually a cracking car - well built and superbly comfy, as Volvos tend to be. Keep an eye out for minor electronic glitches (the cruise control and electric windows seem to be vulnerable points) and if the engine is 'lumpy' when you're switching it off, you're looking at injector issues - expensive ones.

In terms of day-to-day running costs, it should do 44mpg with a manual gearbox (a little less with the optional automatic) and emissions of 175g/km mean you can tax it for €750 a year. That's pricey, but better than buying a pre-2008 model (2008-2009 was the last full year of production) when the engine capacity would land you with a €1,034 tax bill. One running cost to keep an eye on is front tyres. The S60 is quite nose-heavy and has a massive turning circle, things that tend to banjax the front boots. Check any potential purchase for worn rubber and budget for at least a new set every year.

Hi Rosemary,

According to the official figure, you should be getting 33mpg. Bear in mind though that this is almost a ten-year old car, so its performance in terms of fuel economy may have tailed off. Nothing a good service and oil change wouldn't fix though, along with some decent new tyres.

Hi Scott,

Scrappage isn't worth much these days, sadly, but it might be worth having a ring around local breakers' yards and spare parts experts. Often the value in a car can lie in its components rather than the whole, so if things like the body and interior are in good nick, then you may get some value out of selling those off separately.

Hi Michael,

Should be fine, but just check all the electrics and buttons on the inside, as one of the few weak areas on the Vitara is in its wiring. Also make sure that a recall to have the front suspension attended to has been done, and check the service book - Vitaras have rather short 10,000km service intervals so one or two may have been skipped. Other than that, it should be a good 'un.

Hi Ruairi,

As with any folding hard top cabrio the first and most important thing is to check the roof carefully for any problems, leaks, wear and tear. They can be fragile so you want to make sure that everything's working right. 

Secondly, all that roof stuff is heavy (which is why the Eos is so clumsy to drive) so you need to be checking for excessive wear and tear on suspension, tyres, steering etc. 

As for engine, there's no point in going for the 2.0 turbo engine from the Golf GTI as the Eos's porky weight kills the performance. Better to just accept you'll be slow and go for the 1.4 TSI or 2.0 TDI diesel instead.

Hi Leo,

It's always very difficult to analyse such things from afar so we'd advise you bring the car to a good mechanic. It could be something stuck in the tyre or brake disc, it could be a damaged tyre, it could be a worn wheel bearing or something in the transmission.

Best of luck getting it sorted
