Hi Niamh,

We'd never consider those cars to be rivals as the Kodiaq is so much larger inside, but if that's your shortlist, we can work with that.

The Kodiaq is a lovely car, but the RAV4 has the edge in terms of reliability. The Skoda isn't inherently unreliable, but Toyota has an exceptional reputation in that regard.

Nonetheless, I highly recommend you go and test drive both cars for as long as possible, as they drive in a hugely different manner. No point a car lasting forever if you don't actually like how it drives.

Do let us know how you get on.

Hi Teresa,

There's no definitive answer to that, but let's talk through some of it.

First up, while three-cylinder engines might be less balanced and more susceptible to stress when pushed than their four-cylinder counterparts, that's entirely unimportant if you generally pootle around and don't extend the engine to its fullest. And you service it properly.

If you like your car and you don't have to change it, why bother? The more you change your car, the more it costs you in the long run after all.

Nonetheless, if you've got it in your head that you don't trust the three-cylinder engine for some reason, then both the 1.5 Golf and the Corolla are good options.

If all that matters to you is reliability, then it's hard to ignore the Toyota as it has such a strong reputation on that front. We wouldn't expect the Golf to be unreliable as such, but the Corolla is bombproof.

But there's a lot more to a car than dependability and if you already like the Golf, you may well prefer another one over the Corolla. The drive very differently and feel very different, too.

Our advice would be to go and test drive the cars for yourself to see which you prefer, but don't hurry into a decision if there's nothing wrong with your current car.

Hi John,

As you're considering changing car, I'm going to assume you have the previous-generation C-HR. Officially this used 4.8 litres/100km, which equates to 58.9mpg.

The new Alfa Romeo Junior hybrid's official figures are remarkably close, and our tester saw 6.5 litres/100km at the car's international launch. Cars are often driven quicker in these scenarios so that bodes well for the Junior to manage well under 6.0 litres/100km for most drivers.

You'll know yourself how the C-HR does at your hands - in comparison to the official numbers - so make a call on which would be more efficient for you based on that.

For what it's worth, we do really like the Junior. Read our first drive of the Junior Ibrida here.

Hi Cathal,

We'd be fools to suggest that you can be 100 per cent sure you won't have a problem if you do x, y and z, I'm afraid as there's just no guarantees with DPFs.

Saying that, modern cars such as the Tucson and Octavia you mentioned have way better DPF regen logic than they used to, along with more sophisticated exhaust monitoring than before so that's a good start, as is knowing the type of driving that's needed for diesel cars with DPFs – as you've indicated you understand.

You could ask the dealer selling the car (assuming you're not buying privately) for a diagnostic readout with the DPF information, but they're under no obligation to do that and some may not even know how.

My advice would be to insist on a detailed service history, scrutinise that for anything related to the DPF, then ask the seller if any work on the DPF has ever been done. Finally, take it for a decent test drive and, if possible, get someone else to drive it while you follow to observe the exhaust for any excess and obvious regen activity. You may see nothing with such modern cars, however.

The key thing here is to only buy a DPF-equipped car if you spend a portion of your normal driving at higher speeds, allowing the whole exhaust to get hot and work effectively.

Hi Harvey,

I'd thoroughly recommend the Volkswagen Multivan for your needs. It comes in two lengths with seven seats. Both are highly versatile, and the boot is big even if you're using all the seats, especially the one with the “long overhang” body.

We've taken this car away on long holiday trips and it has been nothing short of phenomenal. We're only a family of five, but we all fitted in comfortably as well as a few bikes and way too much stuff for a couple of weeks away camping.

What's more, there are diesel and plug-in hybrid versions available, depending on your needs, and it drives more like a car than any of the actual van-based people carriers out there.

The Tourneo would do the job, too, but it's not as flexible and nowhere near as nice to drive.

Go test drive one for yourself and let us know what you think.

Hi Alex,

Offline you mentioned you'd like something stylish as well as solid and spacious. One of the first cars that comes to mind is the Audi Q3, which is decently practical, has a premium badge and is plentiful for your budget of about €20,000. I'd urge you to stick with petrol power given your annual mileage of no more than 15,000km.

The BMW X1 would do the same job, but it's very difficult to find one that isn't diesel. Same story with the Audi A6 Avant and BMW 5 Series Touring estates, both of which we'd prefer over an SUV. And same thing for the excellent Volkswagen Arteon.

A hybrid-powered Lexus NX would be a good option for you, as would the Mazda CX-5, though neither are as common in the classifieds as the Audi above.

Have a look at some of those and test drive as many cars as you can.

Come back to us if you'd like us to help narrow down your search.

Hi Sharon,

The Elroq is nicer to drive, though the Atto 3 is noticeably faster and more responsive than the entry-level '50' model as it has a more powerful electric motor. The BYD also gets a bigger battery and longer range, but I suspect that isn't such an issue given your short commute.

I prefer the interior, style and quality of the Elroq, and it has a larger boot.

For my money, it would be the Skoda, though as ever we'd urge you to go test drive both to see which you prefer.

Hi Joe,

There's no easy answer to this as every car has a different set of sensors and calibration. In short, the level of ethanol in the fuel can certainly affect a car's emissions, but we're surprised by the jump in the level recorded and don't think that alone would account for it unless something very odd is going on with the engine control unit.

Expert answer

Hi Michael,

If the car suits you now then there's no reason to change it. Sounds like it's barely broken in. Saying that, low mileage at low speeds does not suit diesel engines and their exhaust systems so make sure you take it for a good spin at higher engine speeds regularly to keep it in good condition.

The latest petrol engines are quite efficient, though, so you should go test one out to see what you think of it.

Expert answer

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.
