Hi John,

The plug-in hybrid model would be very cheap to run if you can keep its battery charged up at home or work to carry out those small local journeys you mentioned, but it will certainly be thirstier than your current diesel on longer drives where you can't charge up the battery from an external source. You'll need to do the maths and decide whether you can actually keep it charged up easily.

If you want us to look for alternatives, come back to us with a rough budget, whether you want a new or used car and the number of people you need to carry regularly and we'll see what else might suit you.

Hi Stephen,

I suspect a hybrid would really suit you at that relatively low annual mileage. I certainly wouldn't recommend diesel for you now unless you spend most of that mileage at quite high speed on the motorway. Away from that, a hybrid should be more efficient - and nicer to drive, too.

The Toyota Camry is a lovely option if within budget, but the C-HR is a fine car too. Maybe come back to us with your budget, the type of driving you do and how many people you need to carry on most journeys and we can help narrow things down for you.

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 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 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 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.

Hi Catherine,

As far as I'm aware, they are sprung-loaded, where you push one side of the fuel flap and it springs back out and opens, so maybe there's dirt or something in the mechanism? We can only suggest you try various levels of pressure on the trailing edge of the flap and then release, hoping that it clears. If not, you may have to lever it open, though that could break the mechanism, which would then have to be replaced. If you do go down that route, make sure you protect the main bodywork paint from damage.

Hi Robert,

You should discuss this in more depth with a qualified accountant, but our understanding is that you cannot claim back the cost of buying your private car through the business. If the car is owned by the business and used exclusively for business use, that is a very different scenario, but it doesn't sound to me as if that's the case. If you go ahead with a private purchase of a car and the business is paying back the loan for you then we believe it would be seen as income and taxed accordingly. 

However, as you can claim back all business-related expenses, you should keep a record of all motoring expenses, such as fuel, tax, insurance, repairs, etc. as you may be able to claim back a large portion of the costs if you use the car for business a large portion of the time. 

As I said, it's best you talk this through with your accountant.

Hi John,

As far as we know, there is no fuel station in Ireland selling 98 octane fuel. Circle K has a 97 octane fuel. If you really want to up the octane rating then you'll have to add aftermarket octane boosters each and every time you fill the tank, I'm afraid.
