Hi Kayleigh,

The Rio is very good value under the scrappage scheme so I can understand your interest in it. You are getting a five-door family car for €10,565 (excluding delivery and related charges) under the scheme:

The thing about scrappage is that the discount given by the Government is one part, the discount from the car firm is another; whether or not you will get further discount on top of this from the dealer is debatable. We will check in with Kia to see if you get the same level of discount from an Opel dealer - it may well be restricted to Kia outlets.

Let us come back to you on this one.

There has been a lot of debate about the benefits of hybrid cars, but few would disagree that they are a step in the right direction. The principle of the current crop of hybrids, for those that don't know, is that a standard petrol engine is combined with an electric motor, with the result being better fuel consumption and lower emissions. The original Toyota Prius was the first mass-produced hybrid on sale and Toyota has just released the third generation of the model and it promises to be more refined and cleaner than ever.

There are other alternatives such as the Honda Civic Hybrid, which isn't bad either, or the Honda Insight, while at the top end of the scale Lexus does three hybrids, the GS 450h, the LS 600h and the RX 450h. In the case of the Lexus hybrid technology it's as much about giving the cars higher performance as it is increasing efficiency.

A hybrid is cleaner in so far as official emissions figures are very low. The Prius emits less then 90g/km, which will make it the cleanest petrol car on sale in Ireland. In some cases you could get better fuel economy from a diesel engine though.

With a budget of €40,000 you could easily get into the new Prius when it arrives in October, as the car is expected to cost about €28,000 and this will be a very cheap car to run, so it seems the natural choice. Bear in mind that even cleaner technologies will arrive soon, including those in the Opel Ampera and even a new plug-in version of the Prius.

Hi Alison.

As your car is ten years old this year scrappage seems like the right solution and there are some amazing discounts on offer in addition to the Government's current incentive. The cars you mention are three of the best superminis on the market and because you use the car for quite a lengthy commute a diesel could be the best solution for you.

All three of these cars have diesel options. Opel's Corsa comes with a 1.3-litre 75bhp diesel with emissions now down from 119- to 114g/km. Prices for this start at €15,905 for the three-door version.

The Mazda2 is another very good option. With a 1.4-litre 68bhp diesel, emissions are just 114g/km so again you pay road tax of just €104 per year. The Mazda2 diesel starts from €15,930.

The Fiesta also has a 68bhp 1.4-litre diesel engine and emissions of 110g/km and this starts at €16,645.

All three of these cars qualify for the Government Scrappage Scheme, so would get a discount of €1,500. Much of the additional discounting available on any of these models is on the petrol models however, as dealers try and clear stocks of slow-selling petrol versions.

Of all these three cars the Mazda and the Fiesta are better cars so it would be down to these two in our opinions. We like the Mazda2 a lot, but we'd still say buy the Fiesta based on its looks and the way it drives. The Fiesta has been the outstanding small car over the last few years so if budget allows it is the car we would chose.

Firstly, there are probably more diesel automatic cars in Ireland than you might think, but they tend to be executive models rather than mainstream family cars because it seems that there still isn't a huge demand for them.

Toyota does in fact sell an automatic version of its Avensis. It is a 2.2-litre 150bhp diesel and that costs €35,530. Since you mentioned the Toyota Avensis we must assume that you are after a family saloon or hatchback so for a start you could have a Ford Mondeo 2.0-litre TDCi Style Auto for €32,225 - that comes as a saloon, hatchback or estate.

For you a few quid more you can have the run out version of the Jaguar X-Type 2.2 Diesel Auto for €32,995 or you could have the Mercedes-Benz B180 CDi Auto from €33,640.

There are loads of versions of the excellent Opel Insignia available with a choice of 130- or 160bhp diesel engines in saloon, hatchback or estate body styles. There are 24 different Insignia diesels available in total. Prices start at €30,380. You can have a Renault Laguna 2.0-litre dCi 150 TomTom Edition for €36,890.

A Volkswagen Passat 2.0 TDI with the excellent DSG gearbox will cost you from €35,960 and Skoda will sell you something with DSG for even less. How about an Octavia RS 2.0-litre diesel with 170bhp and DSG for €31,195? For us, that last car is the top choice. However you could stick with Skoda and go much bigger and that would be the Superb. You can have that with DSG and 170bhp for €31,195.

There is a fuel economy penalty in some cases and that is because the traditional automatic transmission has a torque converter. Automatic cars are generally a little heavier too, to the detriment of economy. Saying that, the latest generation of dual-clutch automatics and some of the newest conventional autos have massively improved.

Fuel economy and CO₂ emissions are directly linked, so often the manual version of a car can be in a lower tax band than their automatic siblings, but this is starting to change as mentioned above.
