Hi Ashlene,

In the past the Toyota might have been the automatic choice, but Kia has come on leaps and bounds. Toyota still has the reputation for longevity and troublefree motoring, but Kia is catching up, and its seven-year warranty is real peace of mind for a new car buyer.

Looking at the price lists (of the five-door models - the best-sellers), the Rio is available as a 1.25 petrol model for €15,550 to €16,775 or a 1.4-litre diesel for €18,190. They are all in Band A for tax with emissions of less than 120g/km.

The Toyota Yaris can be had with 1.0- or 1.33-litre petrol engines and a 1.4-litre diesel. Toyota offers far more trim levels, and pricing varies from €15,585 (1.0 Terra) to €19,725 (1.33 Sol). All versions appear to be in Band A as well.

Unless you plan on travelling more than say 12,000 kilometres a year it's best to stick with the petrol versions. The 1.0-litre Toyota is the most efficient, but not by much and the Kia 1.25 engine and Toyota 1.33-litre are largely comparable, though the Yaris engine has a little more go in it.

Kia is more generous with its equipment, but only a bit, and there are more Toyota trim levels to choose from so you can tailor your needs. We'd urge you not to go for the entry-level versions of either though (LX and Terra respectively), as the step up to the next model is well worth it for what you get.

So that's the overview. In terms of our personal opinions we prefer the Kia Rio. It feels and looks more substantial and it drives well. Best bet is to go to a Kia and Toyota dealer and try them both out for yourself.

Let us know how you get on.

Hi Donal,

Before talking about the Renault Fluence specifically, diesel cars in general are better when used on longer trips regularly - for the DPF and other components. We're not aware of any problems with Renault's DPFs in particular.

We asked Renault Ireland about the differences between the 90- and 110hp Fluences and they essentially said that most people are more concerned with saving money, so the 90hp option is, as you've discovered, the best-seller. Here's Renault's statement:

"Both the 90- and 110hp Fluences are great value. It depends on the usage of the car by the customer. €700 can be sometimes hard to upsell these days so dealers prefer to offer the best value, which is the 90hp. It's the customer's choice, and down to what they want to purchase.

Both engines are in Band A and theyare under the same servicing/maintenance programme. For the last point (DPF), this is not an issue on Fluence."

So essentially it comes down to whether you want the extra power. In our view whether it's worth it or not will depend on how often the car is full of people and luggage. In those situations you'll want the higher power output.

Hope that helps - come back to us if you want to discuss it further.

Hi Rob,

For that budget we are assuming you are looking for a second-hand car. The Honda CR-V springs to mind, but the tax could be a little high for you as your budget will get you a pre-2008 version, which came with 2.0- and 2.2-litre engines. How about a five-door version of the Honda HR-V instead? We found this example on Carzone.ie and it looks the part. The 1.6-litre engine means it's not too much to tax either.

There are loads of Hyundai Santa Fes and the smaller Tucson around at that price too, though again their age and engine size might rule them out for you in terms of tax costs. Same story with the previous generation Kia Sportage.

Don't be tempted by older Land Rover Freelanders.

Another good option is the Suzuki Grand Vitara. A quick search showed that there are several 1.6-litre petrol versions with four-wheel drive within your budget, though most seem to be the less practical three-door body style, so you may need to look around to find a five-door example that suits your needs.

The Toyota RAV4 would be a great option, but keeping your tax bill down on a four-wheel drive version with five doors might be tricky. Recommeded though.

Hope all that helps. If you narrow down your search a little come back to us and we'll help you choose!

Hi Jaunkeypersad,

The Kia Rio is available in 1.0 LX or 1.0 EX. Both are petrol and manual and they cost €11,865 and €12,810 respectively. WIth 99g/km emissions they're in Band A, which now costs €160 per annum. Kia quotes 4.2 litres/100km on the combined cycle, which equates to 67.3mpg.

For the same money you could pick up a low-mileage 2010 Toyota Yaris 1.0 or even the 1.33-litre version. There are more grades to look through to see what you're getting for your money, but in terms of economy and emissions, both of those engines sit in Band A as well. The Yaris isn't as economical as the Picanto though, with the 1.0-litre returning 55.4mpg (5.1 litres/100km) and the 1.33 quoted as about 54.3mpg - or 5.2 litres/100km.

The added benefit of buying the Kia new is of course gaining the full seven-year warranty.

Hope that helps.

Hi Greg,

For your €5,000 budget (I'm assuming that's in total, even after you've sold the SEAT) you could get your hands on a late example of the first generation A-Class in A 140 or A 160 guises, both with an automatic gearbox. While the later versions improved, this car does not have a great reputation for reliability so make sure you properly inspect any one you're considering buying and ensure it has a full service history. They're costly to repair.

My money would go on a Honda Jazz. It's compact enough, but has decent space inside. There seem to be plenty on the market at your budget and most of the automatic examples have just 1.3-litre engines to keep costs down. On top of all that the Jazz has an incredible reliability record.

As ever check a car you're buying over thoroughly, but there are a few things to look out for on second-hand versions of the Jazz, as they can be expensive to fix. Check that the adjustment for the door mirrors works and that the car isn't jerky to drive at low speeds.

Let us know how you get on.

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 John, 

The Atkinson engine is a type of engine invented by James Atkinson in 1882. The Atkinson Cycle is where the stroke of the piston can very in length across the four cycles in a four-stroke internal combustion engine. The length of the stroke during the power cycle is increased to promote efficiency, but because this comes at the expense of a shorter intake stroke there is some loss of power and therefore this engine design is best suited for use in hybrid systems where the electric motor can make up for some of the loss of power. 

In conventional four-cycle petrol engines, fuel enrichment is sometimes necessary to cool the exhaust gases, preventing degradation or destruction of the catalytic converters. In an Atkinson cycle engine, compression and expansion are not symmetrical, and the valves close late, delaying compression. This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. As a result, the exhaust temperature is lower than that of conventional engines.

The current model Toyota Prius Hybrid uses a 1.8-litre Atkinson Cycle engine. Adopting the Atkinson cycle and a cooled exhaust gas recirculation system brings significant gains in fuel efficiency and emissions reduction.

Prius 1.8-litre Atkinson Cycle engine

Because the intake valves close late in an Atkinson cycle engine, compression is delayed. This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. As a result the exhaust temperature is lower than that of conventional engines. Cooled Exhaust Gas Recirculation reintroduces the cooled gas into the intake system, further reducing engine operating temperatures.

Other models to use Atkinson Cycle engines include the Lexus CT200h, Lexus RX 450h, Mercedes S400 Blue Hybrid

Hi Justin,

I can't imagine why you would want to come down from a Volvo S8- into a Mondeo or Citroen C5, which are going to both feel inferior to what you have. Are you just simply bored with the car you have and want a change? Both the Mondeo and C5 are 'okay' but their diesel engines aren't as good as the Volvos.

Without fully knowing your circumstances, I would say that if you did want to get something else, then you should perhaps look at a Subaru Legacy Diesel, which for me is the best in its class around that era.

Here is one:

Subaru Legacy

Otherwise, stick with what you have, because both the Mondeo and C5 will feel inferior to your S80.

I hope this helps!

Hi Mary,

I'm afraid there is no definitiive answer to that question. Not only is every engine different, the longevity relies on other factors such as how it is driven and maintained. Honda has a great reliability record though and its engines are some of the best. Assuming it has been well maintained there's no reason it shouldn't reach 200,000 miles without an issue - and further.

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.
