Hi Michael,

You've not mentioned whether you have the Superb or the Octavia, but either way our data suggests that the recommended service interval for the 1.6 TDI timing belt is 140,000 miles (225,000 kilometres) or every four years.

We'd suggest erring on the side of caution with timing belts always, especially on a car that you've not owned yourself from new.

Hi Simon,

Generally speaking all three of these cars are really well built and shouldn't give you any major troubles. The BMW 2.0-litre diesel engine has some well documented and recurring issues with weakness in the turbo, but if you buy one on BMW's approved used programme, you'll get a two-year warranty that should cover you for any issues. The Diesel Particulate Filter issue on the Audi 2.0-litre TDI engine is usually related to drivers doing too low a mileage at too low a speed for the DPF to heat up sufficiently to clean itself - it's a recurring problem on any diesel car bought by someone who fundamentally doesn't understand how diesels work and are best driven.

I'd say of the three, my choice would be the last-gen C-Class. If you're looking at 2013, try and track down one of the last Edition C models - they were loaded with equipment and got an extra AMG body kit and nice wheels too. Superb to drive, cracking 2.1-litre diesel engine (if it touch noisy) and the only drawback is that they're not very spacious in the rear.

Of course, if it's reliability and reliability above all that concerns you, buy a Lexus IS 300h and you won't go wrong...

Hi Philip,

We put this to Kyle Fortune, one of our UK-based writers, as he's the only one of the team that has driven both cars:

"The Jaguar will undoubtedly feel like more of an event initially, the V6's engine and exhaust note are superb, though in some ways it's extrovert sound does promise more than the engine ultimately delivers. It's agile, fast and easy to drive, with an edge that makes it fun, too. The Cayman GTS is a different proposition; it's mid- rather than front-engined, which immediately makes it feel more exotic, even if familiarity - there are lots of Boxsters and Caymans out there, and less F-Types - does lessen its impact. Neither will disappoint, but the Porsche is the more engaging, more polished drive. It's arguably the best sports car you can buy, though the Jag runs it close. Clincher for me would be that the Cayman GTS is available as a manual, the Jag only an automatic."

Hope that's of interest!

Hi Michael,

Basically yes, it's almost impossible to kill an Avensis, but you could also consider a Skoda Superb, Honda Accord or Mazda6 as they will all be similarly reliable. The Mazda is the most fun to drive, the Accord the most luxurious (though they are pricey too) and the Superb the most spacious. The Avensis is a good mix of the three and with so many being on the road, you'll probably get the best value by shopping Toyota. Just avoid ex-taxi ones and it's worth buying an approved second hand example from a Toyota dealer to get a warranty and good after-sales care.

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 there,

No major problems to report. The only mechanical malady that's been reported on the original Santa Fe is a juddering clutch, which was fixed by Hyundai in a recall. Other than that, they have a clean bill of health bar the usual checks. Actually, make sure you check for damage to the underside of the car - despite having four-wheel drive, they're not really designed for off-roading and could easily have been abused by a former owner in that respect.

One other thing - the original Santa Fe is dreadfully crude and nasty to drive. It's well worth trying to stretch your budget to get the post-2006 model, which is a superb car and far superior to the old one in every area.

Hi Mike,

You know what? Most of our answers have to be equivocal, caged in careful speak, allowing for error and trying not to be too definitive just in case we're wrong. In this case though, it's an utter pleasure to say yes, the Superb Greenline really is just an excellent machine and I honestly can't think of a better all round family car. Enjoy.

Hi Seamus,

A Mondeo 2.0 TDCi is, frankly, a great choice - spacious, comfy, well made and superb for that kind of long-haul journey. Just as a suggestion though, it may be worth coming down a class and having a look around, just as a way of potentially keeping your running costs as low as possible. Perhaps a Honda Civic diesel or a Skoda Octavia TDI? Both are massively spacious (so would carry your height with plenty of space behind for baby seats etc.), but would also be a little cheaper to run than the Mondeo, and almost as comfy on the long haul. Worth a thought, but if you fancy the Mondeo, go for it. Buy one with a full service history and you won't go wrong.

Let us know which way you go in the comments below.

Hi Ian,

If it's space you're looking for, go for the Superb, as it's massive inside. No reported electrical problems, but watch for high front tyre wear, paint peeling away from bumpers and flimsy fuel filler caps. There are some reports knocking around of clutches and flywheels failing, but these seem to be very isolated and not a recurrent problem. The Superb's a great car though - smooth and comfy, very spacious and one of the best cars on the market. Go for the Combi estate for even more boot space and nicer exterior styling (in our opinions!).

Hi Paddy,

I have a bit of a soft spot for Saabs in general, but would advise some caution here. That generation 9-3 suffered from a chassis that aged very badly relative to the competition and to be blunt, a Ford Mondeo will drive rings around it. There's also not a lot of space in the back seats. 

On the upside, the 1.9 diesel (a Fiat-General Motors unit) is a good 'un - noisy but very economical and, being a Saab, it's both refreshingly different to other cars, superbly comfy and well able to deal with the rigours of an Irish winter.

Hope that's of some help
