Hi Elizabeth,

Ok, there's a simple answer and a not-so-simple answer. The simple answer is that the Fiesta is more economical. Going by the official figures, you'll get 78mpg on the combined cycle from the Fiesta (and that's for a model without the stop-start system fitted) and 57mpg from the Audi (that's the 125hp engine with a manual gearbox and 16-inch wheels).

Now, the not-so-simple bit. It depends on how and where you drive. If you drive mostly short journeys and mostly in town, then the diesel is not going to give its best, and that 78mpg figure is pure fiction anyway. I'd say in daily driving you'll probably get closer to 55mpg. The Audi, if driven with a bit of care and attention, should easily get 40mpg, even around town. So there's a gap, but it's not so big as you'd think.

The reverse is true if you're doing lots of long journeys at a steady motorway cruise. The Fiesta would come into its own and you''d probably squeeze 60mpg, maybe 65mpg from it. The Audi probably wouldn't get much above 45mpg, maybe a bit less, doing such journeys.

Hi Caroline,

It's too early to tell on Jeep residual values - the brand is well known but still trying to re-establish itself properly in Ireland so it's hard to say quite how values will shake out long term. The Cherokee is nice though, if a touch pricey. Lots of space and it feels rugged. 

The CLA Shooting Brake is also nice, and very pretty too, but I think you'd find it a lot less practical than the A4 - space in the back and the boot is really tight.

Hi Dave,

Quite a bit actually - that 120hp diesel is pretty underpowered in a car as bulky as the A4 and you'll probably notice it most in fuel consumption. You'll have to work it so hard to keep up with traffic that you'll find it quite thirsty. Upgrade to the 140hp if you can.

Hi David,

Do you mean in terms of fuel consumption? Then I'd say about 35- to 40mpg depending on your driving style. If you mean total miles, well it depends how you look after it and how it's been looked after. Cars are generally 'lifed' for between 250,000 miles (400,000km) and 300,000 miles. If you service it and care for it properly, you could potentially get even more...

Hi Diane,

Well, there are expensive things you can do such as buying a different car or swapping out the standard seats for a set of, for example, Recaro or Corbeau bucket seats, but as a bad back sufferer myself I'd suggest booking in to see a good osteopath or physiotherapist. Very rarely will a car seat be the actual culprit - it's more likely that your symptoms are just worse after driving because sitting down for long periods is the very worst thing for your back.

Hi Mike,

The A6 is a cracking choice - reliable, frugal, stylish and hugely comfy, but it's not as sweet to drive as the 5 Series. That said, it is more spacious and if you can track down an Avant estate you'll have one of the best looking cars around. 

If you're concerned about driving on snow and ice there are two avenues you should explore, no matter which car you go for. One is to look into fitting either winter tyres (which you'll need to swap back over to normal tyres in the spring) or all-season tyres, such as the new 'CrossClimate' one from Michelin. Better again, go on a winter driving techniques course. BMW runs one at Rally School Ireland in Monaghan and the skills you'll learn there would get you through even the worst blizzard, no matter which set of your car's wheels are driven.

Hi Jerry,

All three will have excellent resale values, but I'd say the Hyundai has a nose in front in that regard, as it's a big-selling model and the five-year warranty makes it a desirable second hand purchase. 

Of the three, the Nissan is probably the best all-rounder when it comes to driving, the Hyundai is bigger and more spacious and the Kia is better looking (matter of opinion, I realise). It's worth noting though that both the Korean cars are up for replacement shortly wheras the Nissan is brand new and has more cutting edge technology.

Hi Aisling,

Yes they can, but they may not be the most cost-effective. If you're worrying about the diesel particulate filter in the exhaust getting clogged with soot and causing an expensive failure (and that can happen) then don't worry - a quick spin up and back the nearest motorway in a low-ish gear will heat the system up enough to let it burn off the soot and all will be well. Do it once a week for 30 minutes or so and you'll be fine.

The other issue is simple one of cost though. You will spend more money to buy a diesel car than you will a petrol and when you're only doing low mileage it's hard to generate the savings from fuel burn to make up the extra you've spent up front. That's why petrol makes so much sense for lower mileage drivers.

The thing is that the Qashqai can be had with a petrol engine, but it suffers much harsher depreciation when you buy it - so you're in a bit of a catch 22. Petrol is better for your driving profile, but worse for retaining value in this particular model. You may need to expand your search out to some other cars to make your sums add up.

Hi Michael,

If you want to go petrol then there are few better options than Volkswagen's 1.2 TSI turbo, and when it's fitted to the Skoda Octavia, you've got a near-perfect combination. Drive it gently, and you'll probably get very little difference in the overall fuel consumption compared to your old 407. That engine hasn't really been in the market for all that long, so it's a little hard to get a handle on whether or not there are any reliability landmines out there, but in general we've heard nothing bad.
