Hi Stephen

In 2007, the 1.6-litre Passat had 115hp and 155Nm of torque. Top speed was 199km/h, with 0-100km/h in 11 seconds and fuel consumption was 7.6l/100km (or 37mpg).

The 1.9 TDI had 105hp and 250Nm of torque. Top speed was slower at 188km/h and 0-100km/h took 11.7 seconds, but fuel economy was much better at 5.6 l/100km (50mpg).

So, the petrol was a fraction faster, but the diesel offers much better fuel economy. Hope this answers your question.

Hi Liam

A car like yours will retail at a main VW dealer for around €13,500 - €14,000. So, you could probably expect to be offered about €11,000-€12,000 when you trade it in against a Mercedes-Benz, perhaps more if you were trading it in at a VW showroom. Dealerships often have to invest in bodywork and servicing of a trade-in so they don't tend to offer the same as it will retail for and of course they have to try and make some profit too.

Don't get too caught up on how much you are being offered for your car, but rather look at the cost to change. Remember, if you were buying the Mercedes as a straight deal you would probably get a decent discount. This discount may be used against your trade-in to make it seem more appealing.

Pricing a car isn't an exact science, but we would say shop around and don't be afraid to haggle hard!

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.

Hi Pat, 

We contacted Lexus on your behalf. They told us that they now have a policy of "not commenting to media on individual customer / prospect related queries" but they did tell us that but they did tell us that "any prospective customer should note that cars sourced abroad, ie not through the Lexus Ireland channel, do not come with roadside assistance for Ireland whereas cars sourced through our channel come with "Lexus Euro Assistance 24", our 3 year Pan-European roadside assistance programme."

I realise that this doesn't really answer your question, but since you are buying from a Toyota dealer and they would be getting the car through Lexus Ireland I imagine that you would get the standard cover.

You may want to contact Lexus Ireland and seek clarification on this. They can be reached on (01) 4567905. 

As for the car itself, the offer on this model is very good and this is a fine car. I would recommend it.

Hi Jerry,

Do you mean you'd like to fit smaller wheels to your car or fit smaller tyres to your existing wheels? The 'R17' part of your tyre size name means they fit 17-inch diameter wheels. You cannot fit R16 tyres to larger wheels.

If that doesn't answer your question please leave a comment in the box below and we'll come back to you again.

Thank you

Hi Madeline,

It would be great to get a little more information from you on this if possible (you can post it in the comment section below). Are you considering buying a car that was imported and registered a while back and is now being sold on without an NCT or is this a car that has just been imported?

In either case, it's always a good idea to have an independent expert check over the car for you before you commit to buying. The AA provides this service - as do other companies - but even a mechanic you trust would be a good start.

With regards to cars imported from Japan: in my experience, when they arrive in Ireland first, they are generally in very good condition.

As with any used car purchase though, if something doesn't feel right, just walk away from the deal.

Camshaft sensors in most cars are really easy to change, though as with all things under the bonnet we'd always recommend that you bring your car to an expert unless you know what you are doing.

In most cases this work would take 10-15 minutes.

Without the car in front of me, or a workshop manual, I would hesitate to give you more precise instructions, but usually the sensor is held on by just one or two bolts and an electrical connector.

Assuming that is the case, remove the bolts and connector and reverse the procedure for the replacement sensor. Be careful that you do not damage the new sensor.

You should be aware that some cars may need their on-board computer (the Engine Control Unit - or ECU) reset following this operation. Ideally this would be done by a main dealer or garage with the correct equipment.

What has lead you to diagnose a problem with the sensor? (You can reply in the comment box below)

Hi Patricia,

The correct tyre pressures for the Citroen Xsara from 1997-2000 are 31 psi front and rear, but you might want to adjust this upwards slightly if you carry a fully laden car.

Remember to check your tyre pressures every 2 weeks to ensure you have the correct pressure as under-inflation can cause uneven tyre wear and decrease fuel economy. You can buy small devices to check your tyre pressure at places like Halfords or other car parts outlets.

As regards the Xsara owner's handbook, you could go down the route of getting them from a dealer, but we reckon eBay is your best (and cheapest) bet. We found one for around a tenner here

Hope this helps!

Hi Ciaran.

Funnily enough, I was just last week at a tyre event and we got a full briefing on tyre wear, which I knew would come in useful somehow.

Firstly, no this isn't normal wear at all unless you were on a track racing. I take it that you aren't and from what you are saying the wear is even. Usually shoulder wear is a sign of under-inflation. Under-inflation can also lead to tyre blow-outs.

Drivers should check their tyre pressure every two weeks according to the manufacturers. One-sided wear is usually an alignment issue and that doesn't seem to be the case here.

Anyway, we contacted Bridgestone / Firestone on your behalf and they are happy to send out an engineer to inspect your tyres. I have sent you their details. They want to check out if there is a fault and we can take it from there.

What we will say about tyres is that it does not make economical sense to buy cheap ones. They tend to be of lower quality and there is no wisdom in having poor tyres on your car. See how you get on with the engineer and let us know by posting a comment back on this page.

Hope that helps.

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.
