Hi Des,

If you mean the new model, which was introduced in the summer of 2013, then it's generally excellent. Gorgeous to look at (well, we think so anyway) with a fantastic interior, lots of space and excellent economy from the familiar 1.6-litre diesel engine. Citroen's build quality has greatly improved over the past few years, so you shouldn't have any major reliability worries and it's an immensely comfortable car in which to do long journeys. Here's our Irish road test of the five-seat model.

If you're talking about the previous generation then there are a couple of points to keep an eye on. The 1.6 diesel has a habit of developing problems, usually with the turbo's exhaust gas recirculation (EGR) valve. It's a relatively easy fix but it can be pricey so shop around for quotes. Buy as recent a car as you can, as Citroen was constantly improving the build quality as the car developed. Avoid the automatic EGS gearbox - it's awful to drive with and can develop problems with the clutch. Check the cabin very carefully for loose or rattling trim and inspect the bumpers, especially the enormous one-piece front bumper, for any damage - they can be hugely expensive to repair.

Hi Nessa,

Yes, no reason why you shouldn't. Obviously make sure the condition, mileage and history are all in order, but beyond that there are very few things to specifically look for as V70s tend to be built like the proverbial tanks and can easily shrug off high mileage if they're looked after. In fact, according to Volvo's official line on these things, a car with that mileage is only half way through its life...

Things to watch for? Listen out for any unpleasant noises from the front suspension - it's an acknowledged weak point and excess wear and tear is not unusual. Keep an eye on the front tyres too, as they burn through 'em. The engine's only major weak point is its injector system, but you'll know straight away whether yours has problems or not - if it's reluctant to start or belches out great clouds of black smoke when it does start, walk away.

Hi Sharon,

I always think an estate is better for a two-kid family, rather than going for the styling and dynamic compromises an MPV forces upon you. A good idea for that kind of budget might be to upgrade to a more recent Focus Estate. A budget of €6k would get you a high-ish mileage 2008 version with the 1.6-litre diesel engine, which will cost you buttons to run - an easy 58mpg.

It's spacious and comfy and as long as you like your current Focus you won't go wrong. Looking for more of a change? How about a Kia cee'd SW 1.6 diesel EX? Again, cheap to run, really reliable and lots of room in the boot for buggies etc. A cracking family car, that one. Fancy something a bit more rugged? Maybe try a Nissan X-Trail, front-wheel drive with the 150hp 2.0-litre diesel engine. A really terrific car that, but obviously it will be more expensive to run than a smaller estate.

As for trade-in on your Focus, I'm afraid I wouldn't expect too much. Probably only about €1,000 to €1,500.

Hi Michael,

Split decision; if it's a 9-3 running the 1.9 diesel then it's actually quite nice, if a little clunky compared to more modern cars. 

If it's a 9-5 then yes, run. Terribly unreliable car.

Hi Jacinta,

Essentially the old 1.9 TDI Pump Düse engine is just a bit less sophisticated than the newer, cleaner 1.6 TDI common rail engine. That said it's still pretty economical and while you could potentially get 60mpg from the 1.6 you should pretty easily get low-fifties-mpg from the 1.9.

Hi Rory,

Both cars use dual clutch semi-automatic gearboxes, which are pretty slick-shifting, but Volkswagen's DSG transmission just edges it for smoothness and quickness. 

On the emissions front it's rather bad news I'm afraid. If you're buying 2008 model year cars then you're looking at emissions of 189g/km for the Mondeo 2.0 TDCi Powershift and 175g/km for the Passat 2.0 TDI DSG. That means tax of €750 a year.

It gets a bit better if you can spool forward to 2010 when the Passat's emissions drop to 158g/km so that means a tax bill of €570 a year. 

Just for reference, the Mondeo 2.0 diesel auto gets an official 39mpg while the 2010 Passat with DSG gets 47mpg.

To be honest, if you can live without an automatic gearbox you would be better to go for the 1.6-litre diesel versions of either car. Both have decent performance and much better economy and emissions. For instance, a 1.6 BlueMotion Technologies Passat gets 62mpg and has emissions of just 118g/km so tax of €200 a year.

Hi Ger,

To be honest, I would just avoid that generation of Rio at all costs. They're not especially reliable (engines, suspension and ventilation systems all give trouble) and the 1.3-litre petrol engine is quite underpowered, meaning you have to thrash it hard to keep up with the flow of traffic, which wrecks the fuel economy. On top of which the cabin is small, narrow and made of some staggeringly cheap and nasty plastic and they're basically awful to drive.

That generation of Rio was really the last of the truly bad Kias, before the company started to make some really good cars. Go, if you can, for a second generation Rio, made from 2006 onwards in both hatchback and saloon form. They're much more reliable, quite nice to drive and decently economical.

Hope that helps

Hi Jim,

How long is a piece of string? Sorry, but it is actually a tricky question to answer because it kind of involves asking 'which Range Rover?' That is to say that Land Rover's build quality, while it has consistently been improving over the past decade, can still be a touch variable. Many Range Rovers will get through big mileages with no trouble, while others simply won't.

The good news is (and I'm talking about post-2002 models here) that generally Range Rover unreliability has gone from trouble with major items such as brakes and suspension to minor niggles involving electrical components. Basically, if you're buying a Rangie make sure all the buttons work as they should and then budget a substantial amount of money to fix them when they don't. Engines, gearboxes and other bits are generally fine as long as the car has been serviced fully and has history to back that up. You won't get the flawless reliability that you'd get from a Toyota Land Cruiser for instance, but Rangies are certainly more solid than some of the rumours would have it.

Hi there,

Welcome to Ireland! I'd suggest you have a look for a Honda Civic 1.4 petrol automatic. That's probably the best balance between reliability (Civics are very reliable), economy and sticking within your budget. The higher road tax comes from the changeover to a carbon emissions based system in 2008. Prior to that cars were taxed according to their engine size, but the Civic's 1.4-litre petrol engine should keep your tax bills down to a reasonable level. Sadly, there's nothing you can do to change the NCT test - every car requires one every two years once it's more than four years old, and every year once it's more than ten years old. Again, the Honda will help here - they're really well built so less likely to develop problems that would cause you to fail an NCT test, as long as you look after it and keep it serviced.

Hi Brian,

First up, 143,000 miles isn't much for the 1.8 TDCi engine so don't focus on that. This sounds like the car has gone into 'limp home' mode, which could be for a variety of reasons from a faulty sensor to a blocked diesel particulate filter (DPF). You really need the car hooked up to a diagnostic computer at a garage to get to the bottom of the problem quickly.

Let us know how you get on.
