Hi Mike,

The only reason you would specifically buy the efficient dynamics version of the BMW 520d is if you want to pay €104 in road tax, you want the best possible fuel economy and you don't mind changing gears yourself. I'd always prefer by luxury saloon car to come with an automatic transmission and in general, the used car market prefers if you do to. 

We could of course, give our opinions as to what is the best of these cars - but the fact is that they are all in and around the same price, they are all very good and they all offer different things. The BMW is regarded as the drivers car amongst the group although increasingly this is being matched by the excellent new Audi A6. The Mercedes is without doubt the most comfortable of these three cars so if have a very relaxed style of driving then the Mercedes might suit best. 

It does really come down to personal choice. The BMW is the best-seller and that probably won't change for some time. Also you have left out the excellent Jaguar XF, and now with a 2.2-litre diesel it is excellent value. That needs to be considered too.

The arguement for petrol is growing Brendan. While everyone is fixated on diesel the petrol engines are getting cleaner and will come back into fashion. When it comes to fuel economy the gap between petrol and diesel is getting closer and in a lot of cases there is little difference between the road tax.

The 1.4-litre petrol engine in the Passat is more than good enough. So if you want a Passat then you could go for it. There could and perhaps will be less value in the petrol model later on, but if you keep it long enough suddenly this won't become that much of an issue and since you go low mileage then you could keep it for 5 or more years.

Hi Tony,

Given your shortlist, I'd be inclined to go for the new Ford Focus saloon - presumably you mean a 1.6 TDCi version. It's more economical than the BMW and Audi and it'll be four years newer, meaning the security of a manufacturer's warranty. Older BMWs and Audis, as lovely as they are, do start to cost a bit to maintain.

Another car to consider is the relatively new Volkswagen Jetta. It compares well to the Focus.

Hi Gerard,

You didn't specify if you're interested in a new Corolla or a used one, but here are the figures for the latest model:

• Toyota Corolla 1.3 Dual VVT-i (petrol): 5.8 litres/100km (48.7mpg)
• Toyota Corolla 1.4 D-4D 90 (diesel): 4.7 litres/100km (60.1mpg)

Come back to us if this doesn't answer your query.

Hi Laura,

I reckon the Fiat Sedici would be perfect. It is a small car with good fuel economy (from a diesel) that also happenes to come with four-wheel drive, which would make towing really easy. We found one that is within your budget and I reckon it would be a super little car for you.

Hope that helps

Hi Peter,

Diesel cars are now outselling petrol cars by 3 to 1 and of the petrol models that are selling, they are mainly small runabouts. The fact is that the majority of people are being drawn to the lowest possible road tax and in some cases, oddly, this means that they are actually spending more on the car then they really should have. There seems little sense to spend €2,000 - €3,000 more on a diesel car if you are saving €50 a year in road tax and your mileage is low, but that is the way it seems to be happening right now.

The problem with this is that buyers are missing out on on some really good petrol cars. Fiat and Volkswagen in particular have some smart new petrol engines. Take for example the Jetta, which you  mentioned: the new one is out now, but in the older model there was a 105hp 1.2-litre TSI petrol engine and most people baulked at this because they thought it would be too weedy for the car. The same is true of the 1.4-litre TSI, while both are more than capable of adequate performance. 

In terms of fuel economy, sure enough the diesel will usually trump the petrol, but this will only really start to make monetary sense when you do a lot of mileage. It you intend on high mileage, then you are probably better off sticking with the diesel car - Volkswagens are generally quite good at mega mileage, as are Skodas.

We've been getting quite a few queries about DPFs (diesel particulate filters) here in CompleteCar.ie but Mazda appears to be the only brand showing up faults. The Passat though has not been without its troubles and, to be honest, I am not sure if I would be buying a used one with a lot of kilometres on the clock if big mileage is likely.

You mentioned the Jetta, well this one we found would be a top buy. It has just 14,000 miles on the clock, the right 2.0-litre diesel engine and is within your budget. This would be a good buy.

Hi Gerry,

As the Peugeot 508 is brand new there is no way to gauge how reliable it will be. Its predecessor, the 407 saloon, suffered from relatively minor niggles all its life, but first impressions suggest the 508 is of higher quality. The Passat CC, though sold in smaller numbers than the four-door saloon version, has an exemplary reliability record.

In terms of fuel economy and emissions, the 2.0-litre HDi versions of the Peugeot 508 saloon with a manual gearbox emit 125g/km (Band B) and use 4.8 litres/100km (58.9mpg) on the combined cycle. The 1.6-litre HDi models are more efficient, though slower obviously.

In comparison, the VW Passat CC 2.0 TDI (with a manual gearbox again) uses 4.7 litres/100km (60.1mpg) and emits the same 125g/km, so there's virtually nothing to choose between them.

Hope that helps.

Hi Ally,

That really isn't an easy choice, but what we would say from the start is that you have chosen well. These are three fantastic cars and to be honest, any of them will tick the most basic of boxes for you in that they will be reliable, will be comfortable and look good and offer decent value for money. Mazda offer by far the best value when it comes to the scrappage scheme, so if you are watching your budget then this might be the way to go. You can check out the full details of the Mazda3 scrappage offers here. But the most you will pay is €19,495 for a fully specced Mazda3 under scrappage and that is superb value.

Ford Focus (left) & Volkswagen Golf (right)

The two cars you see above are the new Ford Focus (left) and the Volkswagen Golf (right) and choosing between these two would be a bit like asking a parent to choose one of their kids. They both have their individual traits and as such it is hard to pick between them. The new Focus is very good, but I have the hatchback this week and had the saloon last week and actually preferred the saloon. The hatchback has poor visibility out the rear and you do have to pay a lot to get some of the fancy extras that are advertised. Having said that, you will get things like alloy wheels and air conditioning in the models you have chosen. The Golf is superb. We are running a long-term Volkswagen Golf Bluemotion and the fuel economy is great. I prefer the seating position in the Golf. I find that I can get more comfortable in the Golf and the fuel economy is outstanding. It isn't as exciting as the Ford inside, but you know that it will hold its value really well.

Really Ally, all of these cars will suit your needs perfectly. If I was tight on bugdet I would probably buy the Mazda3. If you are very concerned about residual value you have to buy the Golf, while the Focus is the newest car and probably feels the most upmarket.

My favourite of these would be the Golf, but whichever one you pick you will have done well. Again I would say that you need to move pretty fast, because if you want a specific new car it can take a few weeks and there aren't many weeks left in the scrappage scheme.

Hi Declan,

The Passat is a lot of car for a 1.6-litre engine to pull along, so depending on how and where you are driving it then your fuel economy might not be super. Is the car brand new? In the running-in phase economy can be a bit down on post run-in performance but perhaps have a look at your driving style and eliminate that as a possible problem first.

It is possible on the Passat to look at the instantaneous consumption so keep an eye on that and make a note of it and the average values. 

I've been through enough fuel economy challenges at this stage to know that it can be often down to our own driving (and I include myself) in this. Nobody really needs to 'drive' a tonne-and-a-half car down a hill and being a little more delicate with your right foot can make a massive difference (110- vs. 130km/h on a motorway for example). 

Aside from all that, keep a note of the car's performance over 2-3 days then make a conscious effort to change your driving for the next few and if there is no massive difference then perhaps see about getting the car checked over. 

Come back to us with actual figures, mileage of the car and how it is used and we'll try to give you more assistance.

Hi John,

It was developed in-house by the Hyundai-Kia Group for fitment in a wide range of future vehicles. It is a six-speed unit. The driver can choose from two operating modes - fully automatic or ‘Sport’.  For city driving, fully automatic mode is ideal, while ‘Sport’ mode allows for clutch-less manual gear changes for greater driver involvement - either using the centre console selector lever or the new steering wheel-mounted ‘paddles’ (standard on all automatic models). 

The paddles  enable the driver to change gear without taking his/her hands off the steering wheel.  Pulling the right-hand paddle towards the driver changes ‘up’, while pulling the left-hand paddle changes ‘down’.

Although the six-speed transmission is a regular ‘torque converter’ automatic, it incorporates a unique ‘flat’ torque converter, with three planetary gear sets and four pinion differentials - ensuring, according to Hyundai, ultra-fast, smooth and precise gearshifts throughout the engine speed range - and it weighs just 78kg - 20 kg more than the manual gearbox.

Its layout makes this transmission the most compact six-speed unit currently available anywhere in the world according to Hyundai.  It is 54 mm shorter and weighs 12kg less than a regular five-speed unit and boosts fuel economy by up to 12 per cent.  Like the i40’s six-speed manual, the automatic is a ‘filled for life’ maintenance-free unit. 

Automatic transmission-equipped i40s will feature cruise control and Hyundai’s ‘Active Eco System‘ economy indicator to assist with fuel-efficient driving.

Hope that's enough information?
