Hi Mark,

The most common fault with that generation Clio was with the bonnet catch that could fail and allow the bonnet to fly open when driving! Worrying that, and it never triggered a full recall, although Renault did offer to inspect and repair cars for free - make sure the one you're looking at has had that done. Engines are pretty solid, but watch for electrical issues with the windows, the CD player and the engine immobiliser. There are reports of cold starting problems, usually because of a faulty air pressure sensor and the cable-operated gear shift can give problems too. If you have difficulty selecting a gear, then the gearbox is on its way out. Cabin trim is pretty fragile and you need to watch for problems with the brake servos and front suspension arms.

Hi Anne,

It's impossible to diagnose such an issue from afar accurately, but known issues with that Mondeo include:

- Water in the fuel filter or tank (replace the fuel filter to check)

- Poor earth connection under the battery (check the physical connection for rust, etc)

- Fuel injectors out of calibration (requires reprogramming, usually at a dealer)

Another possibility is that the dual-mass flywheel has broken up and needs replacing.

I'd recommend you get the car along to a good mechanic to diagnose it properly.

Hi Una,

We'd immediately suggest you go for the petrol car. The low mileage one will be fresher all-round, plus it's likely it'll last longer before you need to spend money on serious maintenance and repairs. The diesel model may be more economical theoretically, but diesel cars are not best suited to permanent use in an urban environment and we suspect it'd cost you more in the long run.

We conducted some research into this subject in conjunction with Cartell.ie recently if you're interested. Read that piece in full here.

Best of luck

Hi Pat,

To be honest, if badge snobbery were outlawed in the morning, the Kangoo is what we'd all be driving. Massively spacious, comfy and not at all bad to drive, it's the closest modern successor to the original Renault 4. And yes, that's a good thing.

As for reliability, they're pretty good. Being van-based, the mechanical bits are generally of an older design, so the kinks have been long since ironed out and they don't break down much. The only thing to watch for, as on any French car, is the electrical system, which can storm off in a Gallic huff, especially where electric windows are concerned.

Hi Catherine,

Of the two, I'd go for the Focus. Bigger, much better to drive and barely any less economical in day-to-day driving. That generation Corsa was pretty crude, really - noisy and not especially nice to drive.

They're both pretty robust though, which is good, although you should check the Focus carefully for underbody rust as some early cars had very poor weather sealing.

Hi Brian,

BMW quotes a combined cycle economy figure of 35.8mpg (7.9 litres/100km) for the new 740i. Depending on your usage and driving style we'd expect a little worse than that, around 30mpg (9.4 litres/100km).

Hope that helps

Hi John,

I'd say on a trade-in you'd probably get about €2,500 to €3,000 for it. But make sure you do your sums carefully when changing. The cost of change can often outweigh what you're spending on petrol. Maybe practice some seriously economical driving techniques? Take any excess weight out of the car by emptying the boot etc. And get the engine properly serviced and tuned, with fresh filters and new oil.  Check the tyres for condition and correct pressure. You'd be surprised what a difference things like that can make to your fuel consumption.

Hope that helps

Hi Alanna,

Anything pre-2008 with a petrol engine is pretty hard to shift on these days, sadly, so I'd reckon you're looking at a value of possibly as little as €5,500 for the Mazda3 at the moment. To get the best from it, I'd suggest staying within the Mazda family (a Mazda dealer will usually give you a better trade-in on a Mazda than will another dealer) and trade up to a Mazda6 Estate. Loads of space, brilliant to drive, reliable and, with the 2.2-litre 129hp diesel, very economical too. SUV? Do you live up a mountain or at the far end of a rutted dirt road? No? Then you don't need one - stick to the family car market and the Mazda6 size class (which also includes cars like the Toyota Avensis, Ford Mondeo, Volkswagen Passat and Opel Insignia) is  where you'll get the best bang for your buck.

Hi Alanna,

If you like the Mazda, then it would be well worth considering an upgrade to the current-shape Mazda3 with the 1.5-litre SkyActiv diesel engine — it's smooth, refined, very economical and with the usual Mazda reliability. A lovely car. Also worth considering are the Honda Civic 1.6 iDTEC diesel or Kia cee’d 1.6 CRDi.

Hi Mary,

At just 1,500km per year it's highly likely that a petrol car would be better suited to your needs. Diesel cars are usually more expensive to buy in the first place, and new petrol cars are much closer to their diesel counterparts than ever before in terms of fuel economy and tax so in your case the balance tips in favour of petrol. On top of that, diesel cars are designed to be driven at higher speed regularly and they don't take well to a life in town.
