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 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 Dee,

It's possible that you may have legal recourse here, though that's never an easy route to go down. I'd suggest getting in touch with the Competition and Consumer Protection Commission (CCPC) to discuss the situation before you decide.

In terms of general finance rules, if you have paid more than half the PCP value of the car already, then you can by law hand it back and not have to pay anything else. You forfeit any potential equity in the car if you do that of course and if you've paid much more than half, you won't get a refund either. 

In your situation, including a good relationship with the dealer, I'd be tempted to ask for a formal meeting to discuss the problem. Indicate that you're not happy with the car and you want to change it, that you'd rather not explore legal avenues and you'd rather keep your business with the dealer (if that is true). Firmly state that you have no confidence in them fixing the car and that you want to change it. Then let them come up with a solution. If they don't, consider other options as laid out above.

Either way, please do let us know how you get on.

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 Karen,

I'm afraid we are no better-placed to make that decision for you as we know nothing about the car or the dealership. If the dealership says it replaced the belt then it's not likely to be lying about that, and you could pay an independent mechanic to take off the timing belt's top cover to inspect the belt. 

I'd be as worried about oil and filter changes, which are crucial for the long life of an engine.

If you have any doubts, walk away from the deal, as there will be other cars.

Hi Marko,

To be 100 per cent sure, look up your local motor tax office on this page and give them a call. Talk them through the situation and see what they say.

Expert answer

Hi Philip,

Officially, it should be replaced at least every 180,000km regardless of time. There's no harm in doing it more often if you want peace of mind of course.

Expert answer

Hi Martin,

I wouldn't say the market is being flooded with these cars - demand is still far outstripping supply. 

For the most part, these cars represent good value, but go into the deal with your eyes open. If at all possible, get someone in the know to take a detailed look around the car you're looking at, to make sure it's in good condition and that it's identical to a European-market model. 

I'd insist that the car was serviced on Irish soil before taking delivery, and make sure the tyres are ok as well, as these cars could have spent quite a bit of time at sea and at docks here in Japan.

Other than that, check out your insurance before you commit to buying, as insurers can be a little odd about imports at times. 

Expert answer

Hi Martin,

That's trickier than ever to predict right now as prices of used cars have gone through the roof. A dealer would likely try to sell that car for around the €29,000 mark, which means they'd offer you a few grand less as a trade-in. 

Do yourself a big favour though: get offers from several different dealers, as the price will vary.

Let us know how you get on so we can pass the knowledge onto other readers.

The BMW i4 is a great choice by the way!
