Firstly, trading in your car won't be a problem at all if you are bringing the car in against a new model, but you might not get as much for your car as you would have first expected. Selling it privately can be a little trickier these days too as buyers are harder to find because of the lack of available finance, quite simply.

Now, in terms of the car, the SEAT that you are talking about is probably the Exeo, which hasn't been on the market too long. It is a nice car, basically a rebadged previous-generation Audi A4. You have a choice of 1.6- and 2.0-litre petrol or a 2.0-litre diesel. Prices start at €26,690. Go to www.seat.ie for the latest line-up and pricing.

Hi Paul, we contacted Ford in Cork on your behalf, and a spokesperson from their technical department said: "This is not the rev limit of the car and this seems to be an issue with the car in this case. We would suggest that the customer takes the car to his Ford Dealer as soon as possible to be checked."

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.

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
