Hi John,

It entirely depends on how you drive it and where. First up, in terms of actual range you'd get from a tank of fuel, it's worth noting that the Corolla's fuel tank is about a quarter smaller than the Octavia's.

The Corolla hybrid can certainly match the economy of a diesel in certain circumstances, but it really does depend on how it's driven. If you're someone always in a hurry and you like to use all the available performance regularly, then the diesel car is most likely more economical. If you're a gentle driver the Corolla is more efficient.

For lots of motorway driving, the diesel is most likely more economical, but if you only use the motorway a little, I'd suggest the hybrid is better.

Longer term, the diesel model will have bigger maintenance bills as well, so that's something else to consider.

Hi Maura,

It comes down to the wording of the warranty agreement though the onus is usually on the owner to ensure their car is serviced properly. It's highly unusual not to service a car for that long. If you still think you have a case to take, get in touch with the Competition and Consumer Protection Commission for assistance.

Hi Alix,

If you are bringing the car back in yourself there is no paperwork necessary. Your insurance will presumably be in the North, indicating that the car is there. Keep proof of your ferry as well for future reference, but there's nothing else to do at this stage.

Hi Michael,

I'd certainly suggest sticking with diesel given your driving profile so that easily rules out the 530e. Then things are not so clear cut.

There's a huge difference in price between the two used cars you're considering and the new Superb, which makes me wonder what you'd get in the used market for that same €53k (assuming you're buying outright, not on finance of course).

The used cars will have depreciated a little already of course, while the new one will depreciate more, relatively speaking, in its time owned by you. That's the sensible way of thinking, but there's nothing quite like a new car, either so only you can choose that.

Both the Superb and the 520d Touring are great cars, both similarly economical and comfortable, though the Skoda has the edge in terms of rear-seat space. The BMW is a little better to drive by way of compensation.

There's no right or wrong answer, in effect. I highly recommend you go and test drive as many representative cars as you can before you make the decision.

Hi William,

That engine uses a timing chain.

As for things to watch for, there are a few known things:

• Make sure all the doors lock and unlock correctly as the internal mechanism can fail and need replacing
• Ensure you can press the clutch pedal properly and it returns to expected position as issues with the pedal itself and the clutch master cylinder can occur - can mean it's difficult to engage gears too
• If you see the instruments flickering or dropping back to the off position while driving it could mean a new instrument panel is needed
• The gearbox's sensor for it being in neutral can cause starting problems and an issue with the start-stop system so watch out for that - often accompanied by an oil leak from the gearbox

Otherwise it's quite a reliable car. As with all used cars, we'd recommend you drive a few different examples of the same car to get a feel for how it should drive, ask for a detailed service history and make sure you take a proper test drive including some motorway driving.

Hi Ainsley,

In our opinion, the better EV out of the pair is the Tesla Model 3 - but there are caveats to that, and one very big one to consider. Subjective, of course, but the Megane E-Tech is nicer to look at outside and in, and the quality of its interior fittings are also better. It also drives very sweetly, so it's a strong contender.

However, the Model 3 has greater one-shot driving range (both official and real-world), is the more refined car at speed and, once you've tried it you'll realise just how much of a USP the proprietary Supercharger system is for Tesla; there is no finer public recharging experience than this.

The big caveat with the Model 3, though, is the placement of the indicators and the windscreen wiper controls on the steering wheel in the facelifted  version - it's a cackhanded piece of ergonomics if you come to it direct from a car with conventional column stalks.

On top of that, there's a vastly different customer service model at work, as Renault has a nationwide network of dealers you can just pop into, and Tesla does not.

We'd suggest you take all that into consideration while you go test-drive both cars for yourself.

Please do let us know which one you go for.

Hi Brendan,

In your case, it'll likely depend on your driving style. The driving you described really suits a diesel engine if you tend to accelerate up to speed and maintain the speed limit for most of your journey. If, however, you tend to amble along a little slower than that with a more relaxed outlook, then a hybrid will be just as efficient, while also being a little more 'futureproofed'. 

Depending on the model, we'd expect lower overall maintenance bills for a petrol-fuelled hybrid than a diesel.

And while you didn't specify it, a plug-in hybrid might suit you if you can plug the car in at home and also at work, as very few of them can do 100k on a charge.

Finally, it would be remiss of me not to mention that almost any electric car - used or new - would cope with your commute with ease so long as you could charge it up at home. 

Come back to us if you want to discuss your choice in more depth.

Hi David,

It's a tricky time for choosing a new car in your situation for sure, especially given your high mileage. I feel that a diesel would still be a little more economical for you than the latest hybrids unless you keep your speeds down. If you spend most of that at 120km/h then a good diesel is hard to beat from an economy point of view. Saying that, the Corolla and new Civic are both very efficient cars and, if you adapt your driving style to their powertrains, then it is possible to return some trully outstanding fuel economy figures. And it must be said, with one eye on future values, a hybrid might be a more shrewd choice.

In your situation as described, I'd shy away from purely-electric cars for now as well. I'd be worried about relying on the public charging network to support such high mileage.

Hi Bob,

If his vehicle has satnav then it’s not necessary, as it will know where it is and change to suit driving on the right side of the road.

Hi David,

We're big fans of both the BMW xDrive45e and the new iX (though not everyone loves the looks of the latter!).

First up, whether you go for a plug-in hybrid such as that X5, or an electric car, you really do need to have the option to add a home charger. It makes life way easier and keeps your fuel costs down.

Assuming you will install a charger, then either of those cars could work well for you. The X5 could easily cover those short journeys on electric power and you'd never have to worry about delays with the public charging network on your longer journeys. The iX, especially the xDrive50 version (read our review of that here), has a really good range, but very long motorway journeys will still require a little more planning.

However, the iX's cabin and technology are next-generation, making the X5's look out of date already...

I'd suggest going to test drive both cars if at all possible. Failing that, at least try to sit into both so you get a feel for the differences.

Also final word of advice, with all the supply chain issues facing the car world right now, I'd urge you to get your order in as soon as possible, even if you don't plan to take delivery for up to a year.

Best of luck with us - feel free to come back and ask us more.
