Hi Paraic,

First and foremost is the running costs, but I guess they're on the same level as any large SUV-based commercial with an automatic gearbox - they're heavy on fuel and tyres, etc.

Other than that, while the Discovery 3 is proving to be more reliable than its predecessor, it's hardly the most dependable truck of its type. Some cars are perfect, but others have loads of issues, from the electrics to the air suspension and even to full engine failure.

Don't settle for anything less than a full service history and make sure you have the car checked out by someone that knows what they're looking at too.

Hope that helps

Hi Sylvia,

Is that miles or kilometres? Either way, it’s not that much really — just 11,000 miles per year at the worst, which is not a huge amount. As long as it comes with a full and complete service history, I wouldn’t be worried about that kind of mileage at all.

Hi Paudie,

They certainly are, but getting on a bit now, having not been in production since 2006. They’re based on the MkIV Golf, so build quality is generally excellent, but rear seat space isn’t (the boot’s massive though) and if it’s an original Irish car than chances are the equipment levels are going to be pretty basic. You need to check for regular cam belt changes (every 40,000 miles), that good quality oil has been used at service time, that the clutch isn’t too heavy and that the engine isn’t misfiring (that means a faulty ignition coil). Reluctant engine start means a faulty air mass sensor and you need to check for tapping noises at the top of the engine (which means the head needs work, possibly rebuilding) and poor acceleration could mean a faulty crankshaft sensor.

Hi John,

Yes, but at that age you’d want to be checking everything over very carefully and insisting on a full service history. That 1.4-litre engine is both ancient and rugged, but it’s also a bit underpowered (most have only 75hp) so keeping up with traffic can be an issue. No major common faults to report, but as I say with a car that old, check everything.

Hi Sandra,

Both are lovely, and if the prices are more or less the same, we’d go for the 5 Series as it’s bigger, comfier and slightly nicer to drive. Make utterly sure it comes with a full service history, though, and beware of issues with the infamous timing chain.

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.

Hi Mark,

I would imagine so. That’s pretty big mileage right enough, although not so bad on an annualised basis (22,00km a year, roughly), but as long as the service history is chock full of stamps and receipts, and you keep up that level of servicing, then I’d say 500k kilometres is pretty easily on the cards.

Hi Colette,

Keep an eye out for turbo issues on the 1.5 diesel, and listen very carefully for any knocking coming from the suspension. Some of the interior fittings can be a bit fragile too. Other than that, they’re pretty solid, as long as you buy with a full service history. Oh and, yes, they’re economical — you should easily get 45-50mpg in daily driving.

Hi Vinnie,

If we’re talking about petrol 318i and 320i then there’s not an enormous difference — it’s the same 2.0-litre petrol engine, with either 130hp or 150hp on offer. Obviously the 320i’s a bit quicker, but not by all that much, and the 318i is economical if you drive it gently. Reliability is decent, and you don’t have to worry about he timing chain issues that afflicted diesel models, but at that age make absolutely sure that you’re buying a car with full service history.

Hi David,

This Avensis is generally rock solid. The only thing we'd be wary of is the mileage. That seems quite low for one of those of that age. Make sure the condition of the interior backs it up and consider doing a history check on Cartell.ie. These were often used as taxis remember.

General advice for buying any used car is check that all the switches work and get as detailed a service history as you can for the car.

Hope that helps.
