Hi Catherine,

OK, so what you need here is something spacious (kids, even just the one, take up a heroic amount of space, as you know), something economical for all that annual mileage and something comfy so that your buttocks survive all that mileage. I think you should stay with the current rough size of car, as some of the best bargains can be found in the mid-size saloon segment.

First up is a Volkswagen Passat. Ideally, you'd get the 1.6 TDI BlueMotion version, a car in which we once managed to drive from Galway to Glasgow and back on one tank of fuel. Or, what about a Ford Mondeo? You'll easily get a 2.0 TDCi model for that money, and there are very few cars quite so comfy on a long journey. Even BMWs and Mercs can't always match the Mondeo for seat comfort.

Of course, if you fancy the high life, and are prepared to compromise on space a little, then there's the BMW 3 Series. You'll get a 320d or 318d for that kind of budget, but shop around to make sure you get one in a dark metallic, with leather and preferably an automatic gearbox.

Finally, there's the Mazda6. Bit of an unsung hero of this segment, it's brilliant to drive, spacious, good looking and you should be able to track one down with Mazda's excellent 2.2-litre diesel engine under the bonnet. Reliable as it gets, it should chomp through your annual mileage with nary a worry. Find the even more handsome estate version if you can.

Hi Claire,

Depending on specification, history and condition we'd suggest you advertise this for €5,500 and be ready to accept a little less for cash. It's trickier to estimate the trade-in price, as dealers will all have their own agendas. If they don't particularly want your car they'll not give you a good offer, but conversely if they're keen to sell the car you're looking at they may be more generous. The only way to know for sure is to go to a few garages and ask them.

Hope that helps

Hi Dino,

It’s actually a very common engine, the PSA DV4 unit, also shared with Ford, Volvo, Peugeot, Citroen and MINI. It’s a four-cylinder turbodiesel, usually with 110hp, although some later versions had 115hp.

Hi Colm,

Of the ones you’ve suggested, I’d say that the Octavia is the best bet, not least because a Mazda6 or Toyota Avenisis with a 1.8-litre engine is going to be at the very bottom of the range. Your budget should get you an Octavia with the 1.2 TSI turbo petrol engine (which is actually a better choice than a naturally aspirated 1.6 or 1.8) and probably with a 131 numberplate.

Yes, you might have to swallow a high-is mileage, but as long as you get one with a full service history, that shouldn’t be a major issue as the Octavia is a reliable car. Other models worth considering are the Toyota Corolla, VW Jetta, SEAT Exeo (if you can find one) and Honda Civic.

Hi Jon,

So, your average mileage is going to be around 25,000km per year. That’s just on the cusp of needing a diesel, so I’d suggest going for the Mazda in this case, as it will be much more efficient at that kind of journey, and the constant long motorway runs will keep the particulate filter in good order. Plus, the Mazda will likely be more reliable than the Megane in the long run.

Hi John,

Put simply, the RX-8 is usually costly to run and requires a lot of maintenance. Make sure you go into it knowing what to look out for and what it will cost you. In general, you'll want to ensure that the previous owner stuck rigidly to the servicing intervals and regularly topped up the oil. Stay away from cars that have no service history.

It's worth having a mechanic do a compression test of the engine too to check it and ask them to look at how old the spark plugs and leads are, as these are costly to replace.

Other than that, the suspension components are prone to wear, so watch out for slack responses and body control while cornering, which may indicate that it needs new dampers and anti-roll bar bushes.

Best to pay for a full mechanical inspection from an expert in this case.

Hope that helps

Hi Gillian,

With two small kids myself I completely understand your needs. Really, you're probably after something with a much bigger boot, but I assume you like the premium look and feel of the Audi. People in your situation would often upgrade to a bigger car in the same brand, say an Audi A4 or a compact SUV. I've taken a look through Carzone.ie with your budget and needs in mind and here's a list of potential replacements:

- Audi A4: way bigger inside and in the boot than your A3 and significantly more comfortable on the road. Your budget gets you a clean 2010 model saloon or Avant estate with a 2.0 TDI engine.

- Audi A6: much bigger again than the A4, but for the same money you'll get less equipment or an older model - you could afford the saloon or Avant estate though.

- BMW 3 Series: quite comparable to the Audi A4, though not as spacious inside and few Touring estate examples on the used market. Very efficient engines.

- BMW 5 Series: lovely car in same class as Audi A6, though your budget will probably mean a high mileage example. Insist on full service history.

- Honda CR-V: well made family SUV that was designed more for on-road than off-road use. Not all that common, but hugely spacious and reliable. Make sure you go for the newer model that has only just been replaced.

- Mazda6: I'm not sure if you're attached to the Audi badge, but this car is well worth a look. It's massive inside (especially the estate), good to drive, well equipped and reliable. Your budget gets you a low mileage 2011 example too.

- Skoda Superb: no kids will ever kick the back of your seat in this car such is its rear legroom! The boot is massive too and it comes with a range of different engine options. The 1.6 TDI is especially economical. You can afford a 2010-2011 saloon, though personally I prefer the Combi estate.

- Volkswagen Passat: there are a few 2011-2012 Passat saloons available for your budget and it'd be a sensible purchase in some ways. This car is still on sale now new. There aren't many estates about unless you go for the previous generation model.

- Volkswagen Tiguan: a good option, though supply is limited at you budget to 2008 versions. High driving position and spacious all-round.

If you'd like help narrowing your search further, please do come back to us. Also, with such a low annual mileage, it's worth seriously considering a petrol car if you find a well-priced one.

Hi John,

You're in an enviable position. We're assuming you'd like to stick with an open-top car and rear-wheel drive. The Irish market isn't exactly flooded with €50,000 sports cars that match that brief so in your position we'd seriously consider importing from the UK.

Fabulous cars that fall within your budget include:

- Honda S2000 - very reliable and huge fun, though even newest ones are getting on now

- Lotus Elise - one of the most engaging road cars at any price; you could afford a relatively new one with the more reliable Toyota engine

However, we'd put our own money into a Porsche Boxster. You should be able to afford one of the last of the just replaced generation Boxster S. It's very quick, genuinely brilliant to drive and reliable too.

What do you think?

Hi Tommy,

First of all a quick list of possibilities we found on Carzone.ie that we would consider wise buys:

- Audi A4 - Good to drive and plenty about, though you'd have to look at 2005 - 2007 within your budget. Not all that spacious either.

- Audi A6 - Hugely spacious and comfortable, but again you'd have to settle for an older car with higher mileage, which could bring unexpected costs.

- BMW 3 Series - Most examples at this price are 2005-2007. Economical diesels and great to drive, but we'd worry about potential bills - and not as spacious as non-premium brands.

- BMW 5 Series - We'd be sorely tempted by this 2005-2007 model as it's such a great car. Seek out a low mileage example with a full service history and a warranty though.

- Citroen C5 - Comfy big car with decent specification and well-proven diesel engines. Not a huge number on the market, though at least you could afford a 2008 car.

- Ford Mondeo - One of the default options here. It's big, comfortable, good to drive and there are loads and loads about. Relatively cheap and easy to maintain too.

- Honda Accord - Relatively unknown here, but the 2.2-litre diesel engine is a gem and the car is very reliable and comfortable. Look for a post-2008 one to keep your tax bill down.

- Mazda6 - This is probably the car we'd put our own money on. Go for a post-2008 diesel example in a decent specification. It's spacious, well-equipped and great to drive. Reliable too.

- Toyota Avensis - Your budget might get you one of the last of the old models from 2009, though taxi drivers tend to snap these up as well. Make sure you check the history and mileage with Cartell.ie.

- Volkswagen Passat - Plenty about and it's a spacious and comfortable car, but there have been a few niggles with the electrics that'd steer us elsewhere.

There you have it. Come back to us if you'd like more help narrowing down your search.

Hi Fintan,

OK, well you’re kind of cutting across class boundaries there — a Focus and a Mondeo are really quite different cars, with the Focus being smaller, cheaper and arguably more fun to drive, and the Mondeo being more expensive, but bigger, comfier and more refined. That goes pretty much the same for the Opel Astra and Insignia, or the Volkswagen Golf or Passat. So the first thing you need to work out is what you want, and what you need, and whether or not you need the bigger car, or if something more compact will do.

Of the brands you’ve mentioned, the VWs will probably do the best in reliability terms, with Ford being the most enjoyable to drive, and Opel falling somewhere in the middle, but you should also be considering the likes of the Toyota Auris and Avensis (best for reliability), the Peugeot 308 and 508 (stylish, good to drive) and the Mazda3 and Mazda6 (reliable and both very good to drive).
