Hi Niamh,

That's a nice problem to have. Thanks for sending the details of the cars to us via email.

In my opinion, the BMW is the better driver's car and more practical. However, the Mercedes is faster and much sportier looking. It also looks to be better equipped. Both are quite reliable in general, especially with low mileages, so I wouldn't worry about that unduly.

Maybe get a Cartell.ie car history check to verify the mileage and that there is no outstanding finance when you decide which you prefer.

It's imperative that you drive both cars yourself for as long as the seller allows you, as, no matter what we say, your preference is all that matter.

Now, onto money. A figure of €4,500 seems a little steep as a cost to change given the asking price of those cars and the estimated value of your own. I'd be tempted to offer €2,000 and see what they say. Don't be afraid to walk away, as there will be plenty of other cars like this. Also consider selling your car privately for a better price - if more hassle...

Come back to us if you need anything else.

Hi Anna,

Sounds like either the coolant temperature sender unit or an issue with the air flow meter. These items may not be picked up by the diagnostics. In many cars you can just disconnect the air flow meter to test if it's working properly. Try that first. The coolant temperature sensor will be relatively cheap to replace.

Let us know how you get on.

Hi Eoin,

We contacted Volkswagen in relation to your question and 'officially' there does not seem to be a simple solution.

Thankfully there is the unofficial way of doing things and this is something we have experience with having swapped the sports seats in a Mk IV Golf for Recaros from the GTI. A quick search of a certain well-known online auction site reveals that Alcantara sports seats are available, but the shipping costs can prove prohibitive - unless you live near the seller of course.

Our advice would be to contact a large car dismantlers like http://www.traynors.co.uk/ or http://www.eddietorrensinternational.com and see if they have the parts you require. The actual fitting of the seats is just a case of undoing a few bolts and clips with the only problem you might encounter being the possibility of the airbag wiring loom not matching up. This is a simple fix for any auto electrician though and should not cost much to rectify.

We hope this helps.

Hi Andrew,

First of all, the relatively straightforward stuff. There are less Titanium models around than LX and Zetec so it's worth a little more. Autos are quite rare as well so it's not easy to accurately predict the value. However, we reckon you could advertise it for €16,999 as a private sale (and accept a little less) and expect an offer as low as €13,000 in trade-in. Bear in mind though that you should focus on the cost to change if you're going down the trade-in route.

Your car is already at the high end of the mileage range for S-MAXs of that age and if you plan on continuing at the same rate then it may well make sense to change now before the car loses all appeal for dealers - as you've pointed out. 

Hope all that helps.

Hi Piotr,

On the mechanical front the Volvo XC90 has been subject to a number of manufacturer recalls over the course of its life. Depending on what year car you are looking at some of these will not apply but it is worth questioning the dealer about the most recent recalls to ensure that all work has been done.

To deal with the specific car you are looking at, we would suggest have it checked by a competent mechanic before purchasing. If you do not have a friendly mechanic to hand Cartell.ie offers a 'Four star check', which in addition to the detailed history report also includes a full check by an automotive engineer. At €295 it offers great peace of mind, especially when dealing with a high-end car like the Volvo XC90.

Hope that helps.

Hi Eamonn,

Come back to us with your budget, but cars to consider include the Citroen C3, Ford Fiesta, perhaps the Ford Fusion, Honda Jazz, Mazda2 (also called the Demio as an import), Nissan Micra (called the March as an import), Opel Corsa, SEAT Ibiza, Suzuki Swift, Toyota Yaris and the Volkswagen Polo.

That's a long list, I know! It really depends on your budget. Our pick of all that lot would be the Honda Jazz given your requirement for a big boot that's easy to access.

Hope that helps.

Hi Ann,

Our writer Kyle Fortune drove the new ML 250 CDI so I've passed the question to him for answering. This is what he said:

"The base 250 CDI engine in the ML is actually a 2.1-litre turbodiesel mated to a seven-speed automatic to best make use of the engine's torque and power spread. It works relatively well too, so long as you remember you're shifting quite a lot of bulk without masses of power. That said it's got a sizeable 500Nm of torque generated low in the rev range, so the ML 250 CDI is rapid enough in town traffic. It's only out of town - on a motorway slip road when you push it - that you'll perhaps be a bit underwhelmed by the performance. It's all about expectations though, and really, it's a credible performer.

As to the BMW? It's difficult to comment on a car that doesn't exist, but experience of BMW's small capacity turbodiesels does suggest that they typically over deliver on expectations - the 520d for example feels very rapid given its size and weight. How that will translate to the bigger, weightier X5 is questionable, though BMW is unlikely to release a product that's not at the top of its game. We've not heard anything about a 2.5d X5 (officially or not), but it's quite possible given the prevailing economic climate and the ever tightening quest for economy. Downsizing is common so it stands to reason that BMW might be considering it for the X5."

Feel free to come back to us if you would like to know more.

Hi John,

As discussed via email, you need to determine that a) the electric fuel pump in the tank is working and b) that fuel is getting to the engine. These are intricate jobs that only a qualified mechanic should attempt. Given that your car was rear-ended, it's highly likely that the issue is related to the fuel pump in the tank.

Failing all that get an auto-electrician to go through the relevant fuel pump relays and fuses.

Hope you get sorted.

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 Barry,

Thanks for confirming via email that the total budget including trade-in is about €15,000.

One car that immediately comes to mind is the Honda Jazz. They're utterly reliable, easy to drive and park and are available with a decent enough CVT (continuously variable transmission) automatic gearbox. Here's an example on Carzone.ie. Emissions are in Band B so annual road tax is €225. The seating position is more upright in the Jazz than in most small cars so it's easier to get in and out of.

Another option is the Nissan Note. The automatic version's engine is 1.6-litre in size so emissions are higher, putting it into Band D for tax - costing €481 per annum. Otherwise it compares well with the Jazz, with easy access and good reliability in a compact package. Here's an example on Carzone.ie.

The Nissan Qashqai may also fit the bill, though it's a larger car overall, which I suspect is not what you're looking for.
