Hi Kay,

Yes, you should see a considerable saving on fuel, probably in the order of 10mpg at least, depending on how and where you drive. It is worth noting, though, that you will also be looking at considerably higher maintenance and servicing costs, as the 320d is much more sophisticated and high-tech than your Golf and, without careful, regular attention from a specialist they can start giving serious trouble.

Hi Derek,

OK, you haven’t told us the year of your Mazda so that makes it a little hard to value, but seeing as it’s the 1.8 petrol I’m going to guess that it’s around 2006-2007. If so, then I’d say that the €4,400 trade-in offer is actually pretty good.

As to what car to get, if you’re looking for a small hatch then it’s very hard indeed to look past the Volkswagen Golf. It’s one of the world’s best-selling cars for a reason, and as long as you buy one with a full service history and keep it looked after, you should get plenty of years of reliable service out of one yet.

Ditto for the mechanically identical SEAT Leon and Skoda Octavia. The Opel Astra GTC is a fine car in many ways — handsome, good to drive, decent quality, but it was hamstrung by poor diesel engines (other than the range-topping 2.0-litre) and unless you’re looking at the 1.4 petrol turbo model, it’s possibly not the best purchase.

The Focus is definitely a good buy, and that TDCi diesel is frugal to run, but you just have to be slightly cautious about diesel power right now. If you’re not doing big miles, you’d be better off with a petrol car.

Hi Valentine,

You haven’t told us the year of the car, but assuming it’s a 2010 model, then it should be worth in and around €10,000.

Hi Mihails,

Good: economical if you drive it right (i.e: gently), well made, incredibly reliable, roomy, comfortable, cool gear shifter.

Not so good: not pretty, not fun to drive, thirsty if you try and drive it quickly, lots get used and abused as taxis, not good for motorway work (unless you mean the current model).

Hi James,

Assuming that it's the supercharged V6 S, with CO₂ emissions of 213g/km, it'll cost €1,200 a year to tax. 

Expert answer

Hi Jonathan,

Assuming it's the 1.4 VVTi petrol model then you'll pay €385 a year to tax it. As for problems? Not many - the Corolla is spectacularly rugged so, as long as it has a full service history, we wouldn't expect any major problems. Fuel economy should work out at about 40-45mpg depending on how you drive it.

Hi John,

For that model year the XF had CO₂ emissions of 149g/km so tax of €390.

Hi Peter,

It depends on what kind of history the car comes with. If it has a fully-stamped-up service book and a folder bulging with receipts, tax discs and old NCT certificates, and is in obviously good condition, then I wouldn’t have too many worries. If it’s a bit tired and worn looking, and there are gaps in the history, I’d avoid.

Hi Mark,

For the new model G30 5 Series, the CO₂ emissions for the 520d SE are 108g/km, so that means annual motor tax of €190.

Expert answer

Hi Lorraine,

It’ll set you back €710 a year, unless it was imported from the UK post-2008. If it’s an import, then it will be on the current CO₂-based system, which will mean tax of €750 a year.
