There has been a huge move towards diesel cars here in Ireland because of the change to the road tax and VRT laws in July 2008.

Since then, as you may or may not know, road tax and VRT are calculated according to a car's CO₂ emissions and because diesel cars use less fuel than petrol ones, their emissions tend to be lower.

When your father bought the Mazda6 in 2008 it may well have been better value than the diesel model. Now, there is much less difference between the price.

Before we move away from Mazda, there is now a very good range of diesel engines in the new Mazda6 and that might make the most cost-effective swap if he was happy with the car he has because you will most likely get the best trade-in price from a Mazda dealer. However, by the sounds of things he wants a change.

Covering only 10,000km a year we previously might have said that there was no real need to buy a diesel because you would not save the extra price of the car in fuel.

This point remains true, but the difference now is that the market has changed so much to diesel that petrol cars are likely to lose their value faster and become increasingly unwanted by used car buyers, so at this size of car, we would say yes, move to diesel. Also, if you do buy new, your father will most likely benefit from lower road tax.

Without knowing a budget it is difficult to point you in the right direction but from the cars you mention I'm guessing the budget is between €25,000 - €35,000. This does offer a lot of choice.

The 2004/2005 BMW 320d is certainly an option. Since the current shape model came out in 2005, we would encourage you to look at these, or even a 2006. The prices of these are quite competitive at the moment. A 2005 320d SE at a SIMI dealer would probably cost you between €15,000 - €17,000.

BMWs are always tempting to buy used, but you must choose one that has been properly serviced and cared for, because they can become more expensive to put right as they get older. The choice of used 320d models at the moment is vast so if you do go down that route, shop around. It is a great car and with the small mileage your Dad does it is unlikely to end up costing you too much.

If you want to go down the new route, there are a few that would spring to mind. The first is the Skoda Superb. This car is really brilliant and huge too. It is well made and loaded with equipment. If your Dad likes comfort then this will be right up his street.

Our choice would be the 2.0-litre TDI Comfort for €27,805. It is excellent value for money and comes with lots of creature comforts (cruise control, climate control, etc.), a 170hp diesel that is powerful, yet still frugal at 5.8 l/100km. Road tax on this car is €302 per year. For me, if I were heading out to buy a family saloon today, I wouldn't pass the Superb.

You mentioned some other cars there. The Jetta isn't a bad car, but it's been out a few years now and is probably due an update, so I wouldn't buy that new. The Audi A4 is nice. A new one is going to cost you from €34,060 before you start looking at optional extras, so a 2009 model would make sense with all the options already added. €35,000 should get you a nice 2009 TDI version with lots of the toys thrown in.

Please feel free to come back to us with more details if you like (just add a comment below), but for me I would probably have the Superb.

Well you haven’t said what your budget is but there are plenty of interesting cars that are available under the scrappage scheme.

Alfa Romeo’s Mito is a small premium hatchback, and its clean 1.3-litre diesel engine puts it in Band A; the 1.4-litre petrol and 1.6-litre diesel models fall into Band B. Prices start at €18,995 before you take away the government discount.

The Audi A3 with the 1.2-litre TFSI petrol, the 1.6-litre diesel and 2.0-litre diesel all qualify for scrappage, as does the Cabriolet version. The A3 3-door starts from €25,195 before scrappage discount, it’s €26,195 as a 5-door Sportback model, and €32,785 for the Cabriolet version before the €1,500 discount.

The A4 with a 2.0-litre diesel engine in either 120bhp, 136bhp and 170bhp all fall under Band B in either saloon or Avant form. Prices start from €34,060 (€32,560 with scrappage) for the diesel saloon and €36,460 (€34,960 with scrappage) for the Avant. The stunning A5, with a 170bhp 2.0-litre diesel engine, falls into Band B. Prices start at €44,265 (€42,765 with scrappage). You can also have the Audi A6 2.0-litre TDi with 136bhp, which is in Band B. This huge car starts from €39,735 (€38,235 with scrappage). The Audi TT diesel is a really superb car to drive. At €44,175 for the Coupé (€42,675 with scrappage), this is a brilliant buy and that fact that it costs €156 per year to tax makes it all the sweeter.

BMW also has a huge number of models that qualify for the scrappage scheme. Its 2.0-litre diesel is used in various power outputs across the 1-Series, 3-Series and 5-Series and these all have emissions of less than 140g/km, even when fitted with an automatic transmission.

The 1-Series is available with clean diesel engines ranging in power from 115bhp to 177bhp. Prices start at €24,900 for the 3-door 116d, €23,400 with the scrappage discount.

The BMW 3-Series starts from €33,310 for the 316d. All its models get €1,500 off from the government through scrappage. Largest of all is the 520d. Although there is a new model coming later in the year, the run-out models of the 520d are expected to sell well, especially with a price tag of €40,220.

Mercedes-Benz has a number of models that qualify under the scrappage scheme. The standout model is the C-Class Blue Efficiency 200 (136bhp), 220 (170bhp) and 250 (240bhp) manual versions, the E-Class 200, 220 and 250 manual version and the E-Class Coupé 220 and 250 models with manual transmission. Prices start at €36,500 (€35,000 with scrappage) for the C200 CDi, €41,200 (€39,700) for the E200 CDi and €47,700 (€46,200) for the E-Class Coupé E250 CDi.

Finally, what about the Volkswagen Scirocco? You can have the 1.4-litre TSi petrol or 2.0-litre TDi Sport model under the scrappage scheme. Prices start at €25,190 for the Scirocco (€23,690 with scrappage),

To answer your question though, which is fastest? We think it is the BMW 123d Coupe. It has emissions of 138g/km yet has a top speed of 238km/h and 0-100km/h time of 6.9 seconds. This is faster than the Audi TT TDi, which has a top speed of 226km/h and 0-100km/h time of 7.5 seconds.

Hi Julia. Well firstly, congratulations on your new arrivals. With two new babies in your family your car needs will have definitely changed. A friend of mine recently was in the same situation as you and asked me the very same question. They couldn't really cope with a standard five-seater car anymore but by the same token, dreaded the thoughts of getting into an MPV. They felt that by buying one that they had given up on driving something 'exciting and cool' and you can understand that. Even the most modern MPVs can be a little van-like. So, we would steer you in the direction of the Nissan Qashqai+2, which is the 7-seater version of the Qashqai. A 1.5-litre diesel version with 2-wheel drive will cost you €30,450, or if you prefer you could get into a good used version for about €25,000 (2009).

This car will be cheap to run, with low road tax of €156 per year and evidence suggests they are reliable and holding their value too. Please come back to us if you need any more help, but we think this is the right choice for your needs.

Expert answer

When you are starting off you need something that is as reliable as possible and won't cost you too much to tax, run or repair. Usually, the advice would be to make it Japanese because when you are spending a small amount of money you want the most reliable car possible and the Japanese car manufacturers have been making cheap, small runabouts better than anyone else for decades. Something like a Toyota Starlet or Nissan Micra won't be glamorous, but will usually start first time and they are pretty easy to get parts for.

I can understand why you would want the Ka, as it looks funky and its styling has aged really well. If you are going to look at a Ka, there are a few things we would urge you to pay attention to. Firstly, check if this car has power steering because early models didn't have it as standard and one without power steering could be a headache (or rather arm-ache) to park. Rust can also be a problem too so check for this on the door sills and rear wings and on the tailgate. Check the suspension is ok too as this is a costly enough repair to put right. 

Obviously as you are spending quite a small amount of money you can't expect it to be perfect but check these things and that the engine is running reasonably smoothly and this should be quite a nice little car.

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.

Hi Paul,

That is a very interesting question. You only have to look at the difference in pricing through various different genre of cars to see that we have not had cars as cheap here in Ireland in years and even when you compare them to prices in Europe things are favourable. This is of course little solace to those who find obtaining credit virtually impossible.

Manufacturers are constantly streamlining methods of production and there is much greater co-operation between manufacturers in terms of powertrain sharing and platform sharing, but the simple explanation of the reduction in prices here in Ireland is of course the easing of taxation slightly. New cars, as I am sure you are aware, are now taxed according to their CO₂ emissions and this means that cars that might once have been subjected to 30 percent VRT under the old system are now only subject to 16 percent, because of advances in engine technology. When you look at cars like the Mercedes-Benz E-Class and BMW 5 Series now with emissions of less than 140g/km, as long as the present taxation system is in place, prices will remain quite low. Manufacturers are also likely to keep prices low to their retailers as every incentive needs to remain in place to keep sales moving throughout a sluggish global economy.

In answering your question, I would say that the lowering of prices certainly hasn't finished, especially here in Ireland. This year there has been a lot of discounting from manufacturers such as Renault who is aggressively targeting market share. Even when scrappage ends in December I can't see an end to this straight away, as next year, without the scrappage incentives, manufacturers and retailers will need to come up with a whole new set of incentives to draw nervous buyers back into the showrooms.

Hi Paul,

VRT (Vehicle Registration Tax) is the main cost. VRT is chargeable on registration of a motor vehicle in the State. All motor vehicles in the State, other than those brought in temporarily by visitors, must be registered with the Revenue Commissioners. A vehicle must be registered before it can be licensed for road tax purposes.

In the case of cars and small vans, the tax is a percentage of the expected retail price - including all other taxes in the State. This price is known as the Open Market Selling Price or OMSP. The VRO will calculate this tax for you or you may obtain the details online at Vehicle Registration Online Enquiry System.

Full details on how VRT works and all the charges can be found here.

Hope that helps

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.

Expert answer

Hi Laura, that isn't really an easy question to answer, because it really is down to personal choice. Neither of these cars is significantly better overall than the other so it depends on what you are looking for in a car. The Focus is known for having the best chassis and if you like your car to have sharp, crisp and fun handling then you will choose the Focus. The Golf is also quite good to drive, especially the latest version, and it could be perhaps regarded as having a more upmarket image.

Both cars have clean 1.6-litre diesel engines in their best-selling models, with both of these sitting in Band A, which means low road tax. Both are similarly priced too, with the Focus at the moment having perhaps a better offer in the Style five-door model.

Really the only thing we could say is that you should try the two cars for yourself and decide based on your gut feeling. Both of these cars have similar traits and have strong residual values so it'll be a good buy whichever way you go.

The crew cab did enjoy a golden period in the early part of the last decade when there was a considerable tax break, with minimum VRT being charged on them. As a result, sales boomed for a period until this loophole was closed. Sales of the crew cab models aren't as strong as they used to be, especially since the building trade has been so badly affected by the economic downturn.

However, for someone like you they might still make an awful lot of sense because they offer the best of both worlds. They are useful as work vehicles with generous load bays and strong diesel engines that are capable both of high mileage and also towing duties. As everyday passenger vehicles they aren't as comfortable as a regular car and in some cases they aren't even as comfortable as a normal SUV, as most have a pretty basic chassis.

The main choices are between the Mitsubishi L200, the Toyota Hilux and the Nissan Navara. The L200 Double Cab €26,995 new - that includes a significant price reduction recently. It has a 2.5-litre diesel engine that puts out 136bhp. CO₂ emissions of 228g/km mean that it will cost you €2,050 per annum to tax, which is pretty high.

The Navara has a 2.5-litre diesel engine with 171bhp and that is quite a bit more power than the Mitsubishi and it too has emissions of Band G, at 264g/km. Prices start at €34,135 for the Navara Double Cab.

The Hilux comes with a choice of 2.5- or 3.0-litre diesel engines, with 120- and 170bhp respectively. The Hilux has emissions that are in Band E, so you at least save yourself €1,000 in road tax. Prices start at €29,575 for the 2.5-litre Double Cab model.

Having said all that, the best options are likely to be used where there are huge savings.

A 2007 Navara will cost you €16,500 from an approved SIMI dealer: http://bit.ly/d0uIC8 for example

Or a 2007 Toyota Hilux will cost you €19,000: http://bit.ly/bLloV5

Or a 2006 Mitsubishi L200 will cost you €14,950: http://bit.ly/97foEZ
