Hi Rory,

Both cars use dual clutch semi-automatic gearboxes, which are pretty slick-shifting, but Volkswagen's DSG transmission just edges it for smoothness and quickness. 

On the emissions front it's rather bad news I'm afraid. If you're buying 2008 model year cars then you're looking at emissions of 189g/km for the Mondeo 2.0 TDCi Powershift and 175g/km for the Passat 2.0 TDI DSG. That means tax of €750 a year.

It gets a bit better if you can spool forward to 2010 when the Passat's emissions drop to 158g/km so that means a tax bill of €570 a year. 

Just for reference, the Mondeo 2.0 diesel auto gets an official 39mpg while the 2010 Passat with DSG gets 47mpg.

To be honest, if you can live without an automatic gearbox you would be better to go for the 1.6-litre diesel versions of either car. Both have decent performance and much better economy and emissions. For instance, a 1.6 BlueMotion Technologies Passat gets 62mpg and has emissions of just 118g/km so tax of €200 a year.

Hi Donald,

Officialy it's every 100,000 miles (160,000km) or every two years.

Hi Dave,

We're assuming you mean the current 1.6 TDCi version of the Ford C-Max, which has 95hp. It emits 117g/km, putting it in Band A4, which currently costs €200 per annum.

Hi Brian,

First up, 143,000 miles isn't much for the 1.8 TDCi engine so don't focus on that. This sounds like the car has gone into 'limp home' mode, which could be for a variety of reasons from a faulty sensor to a blocked diesel particulate filter (DPF). You really need the car hooked up to a diagnostic computer at a garage to get to the bottom of the problem quickly.

Hi Paddy,

Normally we'd say the Honda every time, but while the Jazz is beautifully built and exceptionally spacious and practical, there's no getting around the fact that the Fiesta is hugely more enjoyable to drive. It kinda depends on your needs. If you're of a practical bent go for the Honda. If driving fun is high on your list of priorities, go for the Fiesta.

Hi Lee,

You've got to keep the engine size down, basically, if you want cheap insurance, but we would also suggest getting something that's good to drive, simply because exposure to good vehicle dynamics early on makes better drivers of us all. So, probably the best balance is to go for a Ford Fiesta 1.25. There are loads of them around and they're cheap to run, decently reliable and very safe. It would also be worth tracking down a Suzuki Swift 1.3, as they're fab to drive and close to indestructible.

However, if even those engine sizes are running the insurance bill up too high, then you need to think  smaller and go down to a 1.0-litre engine. In that case, I'd suggest either a Toyota Aygo (or a mechanically identical Citroen C1 or Peugeot 107) or, if the budget will stretch, a Volkswagen up!, Skoda Citigo or SEAT Mii.

What do you think?

Hi Tom,

Very few, thankfully. Watch for damp carpets as the ventilation system filters have a habit of leaking and letting water into the cabin, and check too to make sure that all of the pipes and plumbing on the diesel engine are correct - there were some problems with them in that regard. There's also a recurring issue with the airbag warning light that seems to be more related to the light than the actual airbag, but it's irritating nonetheless. 

The CO₂ emissions for the 1.4 TDCi Fusion are 120g/km so it'll cost you €200 a year to tax.

Expert answer

Hi Tom,

It's a much smaller car, the Rio. The Focus would be significantly larger and more spacious in the cabin and boot. There is a roughly €6,000 difference between the new prices of both, which should give you an idea of the gap between them. That said, if you don't need the cabin and boot space, the Rio is a cracking little car. Good to drive, good to look at and with that famous seven-year warranty.

Expert answer

Hi Greg,

Yup, they're a good 'un. Ford's reliability record has been steadily improving over the past few years and there are no major reported issues for that generation of Focus. Just watch that a recall to fix a leaking fuel return pipe has been completed and, of course, make sure the car has a full service history. Oh, and as many of these cars will have begun life as company cars, that can mean that they've been well cared for and serviced regularly, but it can also mean that they've been abused by uncaring owners. Check carefully.

Hi William,

Ford is swearing blind that the all-new Mondeo (which has already been on sale for two years in the US as the Ford Fusion) is finally coming to these shores in the autumn of this year. The delay is being explained by the need to move the Mondeo's production line from the Ford factory in Ghenk, Belgium (which is being closed down) to Valencia in Spain.

Many of us car critics have pondered though whether or not Ford is simply stalling to try and let the European passenger car market recover before it introduces such a significant new model. If so, job done it would seem.

The new Passat is a little further away, but should be here by mid-2015 at the latest. Prototypes of the new car are already pounding the roads and test tracks of Europe racking up mileage and it's likely that we'll get a first look at the new car (which will be based on the same MQB chassis system as the current Golf) at the Paris Motor Show this September.

In the meantime, it's worth pointing out that the current Mondeo and Passat are still cars operating at the very top of their game and with new models on the way, it's likely you could argue yourself a decent deal on one.
