Hi Zak,

We always did like the C5 when it was new — big, comfy, quite stylish and it really does look best as an estate. Your ‘friends’ are right in that the Mondeo or Avensis will hold their value better, and there’s no getting away from the fact that an Avensis would be much more reliable over the long term, but at seven years old, the C5 will have the worst of its depreciation behind it now, so as long as it comes with a full service history and you keep it looked after, we wouldn’t regard it as a bad purchase.

Hi Michael,

They’re pretty solid, but watch for issues with the 1.6-litre diesel engine (exhaust filter, water pump, turbo) and the ignition and central locking system. Make sure it has a full and complete service history and don't ignore the warning lights.

Expert answer

Hi Catherine,

A rough estimate of your C4's value should give you a budget of around €12,000 (and you might even do a bit better than that if you're lucky). Even at that level though, there is a plethora of cars matching your description out there. How about we start with something really classy? A BMW 316i maybe? Plenty out there, all priced around €11k and the 1.6-litre engine means reasonable tax and fuel economy even though it's a petrol engine.

Or you might need something a bit more spacious and economical. So we found a Citroen C5 Tourer estate with the 1.6-litre HDi diesel engine. It's a 2008 model so you'll be on the new CO₂-based tax system, it's massive inside and very comfy. Well built too.

Finally, you might fancy something a bit more compact and cheaper to run, and that budget opens up a world of Ford Focus saloons and estates with either the 1.6-litre petrol or 1.8 diesel engines. Simple, spacious, reliable and plentiful, you won't go wrong with that one.

WHat do you think?

Expert answer

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 Gavin,

Here's the checklist for a 2002 Volkswagen Golf (hatchback or Estate):

- Check that alloy wheels have had copper slip grease applied behind them at each service, or the alloy can react with the steel hub and cause corrosion.

- Make sure the headlamps are in good condition, as they're a bumper-off job to replace.

- The rear screen wash-wipe can leak and run into the lock, shorting out the alarm and central locking. The door locks in general can give trouble.

- Most Golf engines need a cambelt change every 40,000 miles (64,000 kilometres). Diesel engines tend to get through a lot of oil.

- Clutch release bearings can wear out easily leading to a hefty clutch action.

- Ignition coils can burn out.

- A whirring noise could be a water pump failure.

- Slow starting or engine management lights often mean a temp sensor has failed.

- A tapping noise on start up may mean you need a cylinder head rebuild.

- If the car has sluggish acceleration it could be a crank or camshaft sensor failure.

- And if there are any issues with any of the main instruments then he whole display has to come out and be replaced.

That's a long list, we know, but if the car you're looking at passes those tests then it's likely to be a good one.

Expert answer

Hi John,

A creaking noise at the back usually means the dampers need replacing, but we don't know of any widespread issue with wishbones, suspension arms and link arms wearing earlier than they should. There aren't a lot of those cars about so data is thin on the ground.

Hi Robert,

There’s lots of choice in that price bracket for an estate. You could go posh with an Audi A4 Avant TDI (you’ll get into a 2007 model for that budget), or big and practical with a Toyota Avensis (2011 or thereabouts), or sporty with a BMW 3 Series Touring. However, you’re probably best going for a Golf — that budget gets you a 2008 or 2009 Golf Estate, which is roomy, practical, reliable, and nice to drive.

Expert answer

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.

Expert answer

Hi Peter,

If reliability and part prices are key, I’d go with the Golf. They’re pretty well built, solidly reliable and not too expensive to service. Nothing much wrong with either the Volvo or the Audi, but you will pay a servicing and parts premium for having the posher badges.

Expert answer

Hi Seamus,

As discussed via email, it's imperative that this car has had a full service history. Assuming there's been just one owner since new then the high mileage is possibly a good sign that this car has had few issues. Its predecessor was notoriously troublesome, though this model seems better. Watch out though for build quality issues like the doors closing properly and make sure the access card works as expected.

Other than that, check every single electric switch and system.

Even so, we'd only feel comfortable going for such a high mileage example if it really was a bargain - or you managed to get a warranty thrown in.

Let us know how you get on
