Hi Philip,

First up, it's worth mentioning that there is not a massive worldwide problem with timing chains. They fail in some cars some of the time, but that does not mean they are inherently less reliable than timing belts. Every car is different in that regard so we'd urge you not to choose a car based on that.

There is no 'norm' - each car maker chooses which to use for a given engine and there doesn't seem to be any trend one way or the other as far as we can seen. 

The 2.0 TDI diesel engine in the pre-facelift Superb definitely used a timing belt, but there's a new engine in the facelifted model ('2.0 TDI evo') and we've not had a lot of information on the timing system. The one photograph of the image I've found shows a plastic cover to the front of the engine, suggesting that it does still have a timing belt.

Hi Brian,

Different versions of the same car can have different equipment levels, which can affect the weight of the vehicle and therefore its emissions. Equally, different model years can have different engine specifications (even if the basic bones of the engine are the same), which can affect the CO₂ rating. Or, of course, one could have a manual gearbox and one an automatic, which can have a major effect on the CO₂ levels.

Hi Andrew,

That’s a tricky one as you’ve not told us the precise cars in question. The thing is, an electric car with a price of €30,000 has probably already had the VRT rebated on it, so you won’t make as big a saving — you’ll only save the VAT, which will represent a discount of around €5,000, bringing the price down to around €25,000. 

With the hybrid, assuming it has CO₂ emissions of under 100g/km, and therefore is in the 15 per cent VRT band, you could make a huge saving. It’s a rough guess, but we reckon you’d save €4,000 worth of VAT and €3,000 worth of VRT, bringing the price down to €17,000. 

Now, these are just rough calculations, and the final, proper figures may differ, but on the face of it the hybrid model offers a better up-front saving, but then you have to work in the potential for much cheaper running costs with an electric car when it comes to fuel and servicing.

Hi Aaron,

Not necessarily. Officially the emissions-based taxation system came into force from the 1st of July 2008. Everything registered after that date is automatically on the CO₂-based system. For cars registered between January 1st and June 30th 2008, it’s a little different. Initially, they would have been taxed on the old engine capacity system, but if the tax cost would have been lower under the CO₂ system, then the car should have been switched over at first renewal. If it hasn’t been switched by now, it probably means that it’s more affordable to tax on the old capacity system, so has been left on that one.

Hi Harry,

The most likely culprit is that there’s some electrical item draining the system as you’re driving. Or, possibly if you’re only driving for short hops, the engine is still in its warm-up phase and can’t be shut down by the stop/start. Or, and this is a wild guess, Land Rovers often have flakey electrics. 

Maybe read our Why won't my car's stop-start system work? feature for further understanding. We get a lot of questions like this.

Hi Martin,

The price looks reasonable — about in the middle of the road for a 2015 A4, so the true value will depend on the car’s specification and its overall condition. A figure of 72,000 is a very reasonable mileage if it’s in miles (and if it is in miles check to see if the car was imported from the UK — that’s not necessarily a problem but you’d want to be a little more wary about its history if it is an import) and exceptionally low if it’s in kilometres. If it is 72,000 kilometres, rather than miles, I’d actually be slightly suspicious of that figure, as it may have had the clock turned back.

Audis are well-made, and generally very reliable and that 2.0-litre TDI engine is solid, but make sure that it’s had its software recalibrated to reduce its pollutants (the changes that were mandated after the diesel scandal became public) and make sure that it has a full and complete service history — these are complex cars that need looking after, so if there are any gaps in the service record, I’d walk away; there are plenty of other A4s out there.

Hi Muhammad,

It’s a rough guess (you can never quite tell which way Revenue is going to go with some cars), but I’d say you’ll pay between €900 and €1,000 VRT on that.

Hi Robert.

Stop-start systems have a mind of their own — literally. They’re designed to only stop the engine when demand for electrical supply within the car falls low enough that it’s safe to do so. So if you’re running the air conditioning, for instance, or have the heat turned up, or if the engine is still in its warm-up phase, then it will either not shut the engine off at all, or will only shut it off briefly. Driving style also plays into it, as does where and when you’re driving. It also depends on the battery condition, so if you’re concerned about the short stop-start times, it’s worth having the health and charge level of the battery checked.

Finally, as we get so many questions on this subject, we put together a quick feature on it for your interest: Why won't my car's stop-start system work?

Hi Kira,

There are a couple of places you can hire a DeLorean from, but there are a LOT of terms and conditions to go with it. The first place to try is www.starcarhire.co.uk, which has a Back to the Future-style Deloran available for hire, but which will only chauffeur the car for you — you won’t be able to drive it.

It’s also worth getting in touch with the DeLorean Ireland Owners’ Club at www.delorean.ie as some of its members hire out their cars for special events, and they would certainly be able to point you in the right direction. As for prices, I’m afraid it’s very much a case of you’ll only find out when you ask...

Hi Philip,

Well, you’re right about Toyotas being reliable. In fact, if reliability is your ultimate goal, then Toyota, Honda and Subaru are usually your safest bets. That said, Skoda is rarely that far behind the big Japanese names in reliability terms, and often is the best-performing European marque in that regard. In terms of load capacity, the answer is almost, but not quite. The roomiest boot in the in the Toyota range right now belongs to the Corolla Touring Sports estate. Now, this is one of our favourite cars right now — good looking, good to drive and with a seriously frugal and future-proofed hybrid engine, but with a 598-litre boot, it’s some 62 litres short of the Superb Combi. Still worth considering though, as, if you can live without the extra litres in the back, then it’s a more cost-effective purchase than the Skoda.

Another alternative is the new RAV4 Hybrid. Again, this is smaller than the Superb in the back — 580 litres when loaded up to the windows — but the boot is big and square, and again the hybrid engine is frugal and it’s got reliability on its side. 

Worth remembering though that Skoda is refreshing the Superb this year (order books are open now for delivery later in the year) and there will be a hybrid, a plug-in hybrid in fact, this time around, so it might be worth waiting for that before making a final decision.
