Hi Keith,

It really just depends on two things; her driving style and habits and what kind of condition the car is in. If it's in good nick, her average mileage is quite low and she's able to maximise the economy from that engine, you may just be better off spending a little bit of money getting the car thoroughly serviced and spruced up and sticking with it. If though her mileage is creeping up or you feel that the car is starting to age then it could well be worth trading in for a newer Passat. The current model is essentially the same car, but updated and re-skinned and the 1.6 TDI diesel gives it terrific economy.

Hi Terry,

We don't actually have insurance groups for cars in Ireland; it's down to the driver and their experience and claims history when it comes to setting the price. If it helps, that model varies from Group 18 to Group 21 in the UK depending on whether it has the 109- or 115hp version of the 1.6-litre diesel engine.

Expert answer

Hi Riccardo,

No, it's not. You're quite right that the 1.5-litre CDI engine in the A 180 model is derived from Renault's long-serving dCi engine, but the 220 CDI unit is Mercedes' own 2.1-litre four-cylinder engine in 170hp trim.

Hi Jimmy,

As far as we can find, none. The highest emissions model in the Polo range is the GTI and that has a CO₂ rating of 139g/km, which puts it, albeit only just, into Band B2, and tax of €280 a year.

Did you find otherwise?

Hi Ruairi,

As with any folding hard top cabrio the first and most important thing is to check the roof carefully for any problems, leaks, wear and tear. They can be fragile so you want to make sure that everything's working right. 

Secondly, all that roof stuff is heavy (which is why the Eos is so clumsy to drive) so you need to be checking for excessive wear and tear on suspension, tyres, steering etc. 

As for engine, there's no point in going for the 2.0 turbo engine from the Golf GTI as the Eos's porky weight kills the performance. Better to just accept you'll be slow and go for the 1.4 TSI or 2.0 TDI diesel instead.

Let us know how you get on

Hi Patrick,

I really like the S80 - a lovely big comfy thing, ideal if you're doing lots of long journeys and that 1.6 diesel engine is super efficient; you could get up to 1,500km from a tank of fuel. 

Reliability shouldn't be a major issue once you make sure that the car has a full service history. Like any executive saloon there's a lot of electronic toys in there and if it's been well cared for, there's less chance of them going wrong. Keep an eye on the service schedule to make sure that the engine has always been topped up with the highest grade of oil and if it feels down on power or sluggish when accelerating, it's most likely the exhaust gas recirculation (EGR) valve.

Hi Tony,

New or old? Frankly, they're all good. The current car is slick, massively spacious, lovely to drive and, aside from occasionally poor fuel economy, terrific ownership prospects. 

The previous generation is all of that with slightly less slick styling inside and out. Make sure you go for the later, post-facelift model that uses Mazda's own 129- or 180hp 2.2 diesel engine.

Finally the original - made from 2002 - it's a landmark car. Reliable, fabulous to drive and quietly handsome. They're super-cheap now and a perfect low-budget purchase.

Expert answer

Hi Michael,

If it's short trips and city driving then you're probably better off with the petrol model. It's significantly cheaper than the diesel version, which gives you plenty of budget to buy fuel and pay the slightly more expensive road tax. One word of warning though - from personal experience it can be almost impossible to move on a Mk1 petrol Qashqai when the market is so diesel-obsessed. Several people I know have had to take a bath on second hand value when it came to trading in a first gen 1.6 petrol Qashqai so you need to be aware of that. The new 1.2 petrol turbo version should by rights fare better because it's so efficient but with the market still being diesel mad, you need to be careful.

Hi Allan,

OK, here's a question that has completely stumped us. Only 39 Costins were built and they don't come up for sale much, so I'm afraid we just don't know where to begin. Can any of our other readers help us out here?

Expert answer

Hi Rafal,

There are no problems that suggest themselves as a likely culprit. The Bora is more or less mechanically identical to the Golf, so has the same solidity and suffers the same basic niggles - if there were a problem causing Bora NCT failures, it would be happening to Golfs too. Certainly, Volkswagen Ireland is unaware of any particular Bora issue when we asked for a comment. 

The only thing we can think of is that the Bora has slightly stiffer, sportier suspension than the Golf and that could potentially lead to wear and tear on things like bushings and track rod ends. Given the age of the cars you're looking at, that could be the problem, although in fairness, any 10 to 14-year old car could be suffering from that kind of problem, especially if it's an original Irish car.
