Hi Dave,

Given you'll be on the motorway for an hour each way, presumably a few days a week at least, a diesel car seems to make the most sense in your case.

We'd also suggest that you stick to a car rather than an SUV as it will be better to drive, generally more comfortable and definitely more efficient.

Scouring the classifieds for options, here's what we reckon might suit:

Honda Civic 1.6 diesel
Hyundai i40 1.7 diesel
Kia Optima 1.6 diesel
SEAT Leon 1.6 diesel
Skoda Octavia 1.6 diesel
Volkswagen Passat 2.0 diesel
Volkswagen Golf 1.6 diesel

Come back to us if you'd actually rather stick with a premium marque. The above are a good bet in general when it comes to reliability, though as ever, take your time to choose a good example with a detailed service history, and take test drives as well.

Hi Niall,

With your requirements and budget, you'll certainly be looking at a used EV rather than a new one, which may mean buying a car that doesn't have much of its original regular warranty remaining (as the industry default is three years - though there are exceptions). However, the car makers include a longer warranty on the drive battery to reassure buyers of their longevity. Typically, this is for eight years and 160,000km (from new), though the precise figures vary from model to model.

You've not specified if any of your kids are in small seats or boosters so we assume three of them can fit across in one row of a normal car (do come back to us if we're wrong on that as that will limit your options considerably).

In terms of your driving use, and assuming you'll get a home charger to cover day-to-day charging, you're going to have to plan to use the public charging network on your longer journeys. Very few used EVs in your budget will do 400km on a charge all year around with five people on board.

Most should require just one top-up on that trip, however, taking no longer to charge than it will to get the kids all out and into the bathroom and for you to grab a coffee.

I'm sure you'd have to stop a few times on a 1,000km trip regardless of charging up the car.

Taking a look at what's on the market for under €25,000, here are some options we'd recommend:

Cupra Born: This is a five-seat, five-door hatchback about the same size as a Volkswagen Golf on the outside (and indeed it's the same underneath as the Volkswagen ID.3), but it has way more rear-seat space. Your budget gets you a 2022 example using the 58kWh battery pack, which means a realistic range of about 300km between charges.

Hyundai Kona Electric: The Kona is a five-door, five-seat crossover you should find as new as 2023 available within budget. That's the last of the previous-generation model. It's smaller in the boot and back seat than the Cupra mentioned above, but it is efficient. There are even some available with a 64kWh battery for a realistic range between charges of nearly 400km.

Kia e-Niro: This is another five-seat crossover, actually sharing its underpinnings with the Hyundai. However, the Niro is noticeably bigger inside the cabin and boot. There are loads of 2022 examples around with a 64kWh battery - meaning a real-world range of nearly 400km again. Sidebar: the Kia e-Soul is a stylish alternative sharing most of the same components, though it's less practical as a family car.

Skoda Enyaq: The Enyaq is a fantastic family car with much more space in the cabin and boot than all of the above. Sadly, there are very few about at your budget, though we did find a couple so it might be worth holding out for. The compromise is that you'll only be able to afford the 58kWh model, which should manage a little over 300km between charges.

Volkswagen ID.3/ID.4: The ID.3 is VW's equivalent to the Cupra Born above and there are more of them about, most with the same 58kWh battery. Saying that, we did find a few with the 77kWh battery pack, enabling a much longer range. The ID.4 is notably larger inside and comparable with the Skoda Enyaq. It's not common within budget though.

Hi John,

You've not mentioned which gearbox specifically, so we'll assume you mean the DSG automatic. These can develop faults with the 'mechatronic' unit that controls gear shifting etc. If that has to be replaced then it's expensive, though sometimes just changing the transmission fluid helps.

That needs to be done regularly in DSG units using the 'wet-clutch' setup. Those with the dry-clutch system don't need such maintenance.

If you've thinking about buying a car using a DSG transmission, then make sure you take it for a decent test drive through the full speed range up to motorway speeds and monitor the gear changing for judders or other issues. If possible, spend some time in stop-start traffic as well as that can cause the clutch packs and mechatronic unit to overheat if they are weak and you'll soon notice if something isn't right.

Saying all this, the DSG transmissions aren't necessarily bad designs, you just need to ensure the one you're buying is still operating properly.

Hi Des,

Our information is 240,000km or 15 years on that car, but in truth, the dealer should know best. A car manufacturer wouldn't just change the interval for the sake of 'lining its pockets' as you've described and it's not unusual for changes to the interval to happen in a car's lifetime as experience is gathered. 

No harm double checking that information with a few other Volkswagen dealerships and, as the car is out of warranty anyway, you can always consider getting the work done at an independent garage.

Hi Ahmed,

It really depends on where you do most of your driving, and how many people you tend to carry around. The 115hp model is fine around town and at lower speeds if you're on your own, but if you have three other people on board regularly, or you often drive in hilly areas, you'll appreciate the extra performance of the 150hp engine. There won't be much of a difference in the real-world fuel economy.

Hi John,

It should be changed at least every 210,000km, regardless of time.

Hi Avdirrahman,

It's every 210,000 kilometres regardless of time.

Hi Brian,

It’s difficult, to be honest. There are some online resources for NOx emissions, but they’re flaky at best, and the only number that Revenue will accept is the one on the car’s Certificate of Conformity. The best figure we can find for a 2017 Golf 1.6 TDI is 130mg/km of NOx, but that’s not necessarily the 100 per cent accurate figure for the car at which you’re looking.

Hi Gavin,

In terms of roominess, there’s no contest — the Civic is the winner here, by a long chalk. Bigger in the boot, too. Actually, we really like the current edition of the Civic. In terms of exterior and interior design, the Golf is ahead, but the Civic is actually the sweeter of the two to drive, and being a Honda it will almost certainly never break. Go for the Civic.

Hi Mark,

If you’re prepared to wait a bit, there is an all-new Octavia RS coming, which will be available as a plug-in hybrid with 245hp. Now, it will depend on how you rack up those 30,000km as to whether a plug-in hybrid would suit you — if it’s all motorway miles then probably not, but if you do a lot of short-hauls around town, and can charge at home, then it could be ideal.

There’s also the diesel version of the new Ford Focus ST to consider, the new Golf GTI and SEAT Leon Cupra (all sharing their bits and pieces with the Octavia, of course), or what about a Hyundai i30 N — one of our favourite hot hatches? A few reviews to help you decide:
