Hi Christopher,

First things first: go for automatic. The fuel economy won't be as good, but there are far more on the market and the manual version retains the foot-operated parking brake, which is madness. It should return about 35mpg.

In general it's a reliable car, though check all electrics and if the gearbox is jerky walk away. Also listen out for suspension knocks. Insist on a full service history or find a car that has it.

Hope that all helps.

Hi Gerry,

In general the new C-Class is proving quite reliable. There are a few known minor issues that should all be covered by a dealer for previous recalls so it's worth checking with a Mercedes-Benz dealer and the chassis number of the car you're looking at. These include software glitches for the automatic gearbox causing slow gearchanges. Make sure you get the spare key too, as these sometimes fail.

Hope that helps

Hi Philip,

That generation of Ford Mondeo was fitted with timing chains so no need to worry.

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."

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.

If you need help narrowing the search down further come back to us - and let us know what you go for.

Hi Greg,

For your €5,000 budget (I'm assuming that's in total, even after you've sold the SEAT) you could get your hands on a late example of the first generation A-Class in A 140 or A 160 guises, both with an automatic gearbox. While the later versions improved, this car does not have a great reputation for reliability so make sure you properly inspect any one you're considering buying and ensure it has a full service history. They're costly to repair.

My money would go on a Honda Jazz. It's compact enough, but has decent space inside. There seem to be plenty on the market at your budget and most of the automatic examples have just 1.3-litre engines to keep costs down. On top of all that the Jazz has an incredible reliability record.

As ever check a car you're buying over thoroughly, but there are a few things to look out for on second-hand versions of the Jazz, as they can be expensive to fix. Check that the adjustment for the door mirrors works and that the car isn't jerky to drive at low speeds.

Let us know how you get on.

Hi Antoinette,

First of all it's always worth remembering to focus on the 'cost to change' rather than the trade-in value alone. Your current car is unlikley to be worth quite €1,000 to a dealer so bear that in mind. If that gives you €5,000 in total to spend then you could potentially afford a 2005 Toyota Avensis. However, that price will get you a high mileage example so it may be worth going for a 2003/2004 example in good condition with low mileage.

I reckon you're better off with a petrol version if you're looking at an Avensis of that age. It was before the changeover to emissions-based taxation in July 2008, so the 1.6-litre petrol model was very popular - and is therefore in plentiful supply on the used market. Tax is cheaper too than the diesel of the same age due to it being calculated on engine size.

Along with that, 11,000 miles per year is not quite high enough to justify the potential extra cost of a diesel car in my opinion.

Hope that helps

Hi Mike,

The only reason you would specifically buy the efficient dynamics version of the BMW 520d is if you want to pay €104 in road tax, you want the best possible fuel economy and you don't mind changing gears yourself. I'd always prefer by luxury saloon car to come with an automatic transmission and in general, the used car market prefers if you do to. 

We could of course, give our opinions as to what is the best of these cars - but the fact is that they are all in and around the same price, they are all very good and they all offer different things. The BMW is regarded as the drivers car amongst the group although increasingly this is being matched by the excellent new Audi A6. The Mercedes is without doubt the most comfortable of these three cars so if have a very relaxed style of driving then the Mercedes might suit best. 

It does really come down to personal choice. The BMW is the best-seller and that probably won't change for some time. Also you have left out the excellent Jaguar XF, and now with a 2.2-litre diesel it is excellent value. That needs to be considered too.
