Hi John,

Your Octavia's boot is rated to 600 litres, we believe, which is difficult to match unless you go for a much larger car. The Volkswagen ID.7 Tourer, for example, holds a little more than that, but it's out of budget. Same story for the VW Tayron eHybrid (PHEV), which has a bigger boot again.

Those cars are still relatively new, so you can't afford used versions yet, either, though we did find a selection of second-hand Skoda Superb PHEVs on the market within budget. They're massive in all directions and might well suit your needs, so long as you don't mind going for a car that's two to three years old.

The VW ID.4 and Skoda Enyaq have comparable boots of well over 500 litres and are in budget – though there's much more choice in the ID.4 lineup for that money.

Last but not least, and assuming you have nothing against buying an SUV, the Hyundai Tucson PHEV has a boot of about 560 litres and is within budget.

Let us know what you think of these suggestions.

Hi Emma,

No, it's a traditional 'dry' belt in that engine.

Hi Doteen,

A car's history and how well it has been serviced is important no matter what fuel type it is. The added complication with modern diesels is that their DPFs – and other components - can clog up if they're only used for short trips. I don't believe where you buy the car has any bearing on that. It's all about how the car was used.

Make sure all the warning lights are working and going off when the car is running, insist on a detailed and complete service history and take the car for a decent test drive (again, regardless of the fuel).

A diesel car will be far more economical than a petrol one when it comes to towing and for the most part will be better suited to the job in terms of low-down pulling power (torque).

Nonetheless, if you'd prefer a petrol car, that's entirely doable. Just don't go for a small-engined, lightweight car and expect it to do a good job. Cars such as the Ford Mondeo, Skoda Octavia, VW Passat and others all came with powerful turbocharged petrol engines, though they're much rarer and hence harder to find than the diesel equivalents.

Hopefully that has given you some food for thought but come back to us with more information on the weight of the caravan you're buying and your budget for the car and we can help further if you need it.

Hi Kieran,

That's frustrating on the resale value of your car, but we're in no better position than the dealers you've spoken to and they hold the 'power' in that regard so the cost-to-change will all come down to the deal any one showroom is willing to make. Anecdotally, you'll get a better deal if you go back to a BMW outlet, but it doesn't sound like any BMW is on your radar this time around. 

The three cars you've listed are decent enough, but I'd strongly urge you to test drive them before you make any decisions as they'll all feel a big chunky and heavy next to your BMW i4. 

Have you considered Polestar at all? Both the Polestar 2 and Polestar 4 are within the same price ballpark as you're looking and are both great to drive with a bit of an SUV vibe. The Polestar 2 has been around for a while (I own one as it happens) but it was significantly upgraded last year for more performance, spec and efficiency. It's now either rear-drive or all-wheel drive.

Again, take the time to go and test drive all of these cars before you bother trying to make deals, as the driving experience of the BMW i4 is a hard act to follow.

Hi Niamh,

It is highly likely that there would be running electronic and software updates on the Kodiaq to try to iron out the early issues reported, though of course there's no guarantee.

I would certainly raise it with your Skoda dealer and ask for a confirmation of your car's build date before agreeing to buy it. E.g. if it's an older car that has been sitting around somewhere, you may wonder if it has been built with the latest updates.

We can't give you any more reassurance than that I'm afraid.

Hi Bill,

Obviously a plug-in hybrid (PHEV) makes most sense here as those come with ultra-low CO₂ emissions to help keep the BIK down. Though we would only recommend you buy one if you have a way of charging it up at home or at work on a very regular basis.

If you like your Audi, then the new Audi A5 e-hybrid makes for a good option. It can be had as a Sportback or Avant estate within your budget and it's a really lovely car. The e-hybrid system allows for a long electric range and low emissions, too. Read our review of the A5 e-hybrid for more.

The BMW 330e is another excellent premium PHEV within budget, both as a saloon or Touring estate. It's not as fresh-faced as the Audi A5, but it's still a good car. Read our review of the updated BMW 330e if you're interested.

Our next port of call would have been the Skoda Superb, but for some bizarre reason it's only offered as a PHEV in Combi estate format, so if you don't want an estate, then it's not for you. If you're open to the idea, however, it's a considerably larger car than the BMW and Audi mentioned above, if not as interesting to drive. Within budget, however, is the range-topping L&K variant, which puts the Audi and BMW to shame in terms of what you get for your money. Again, read our review of the Skoda Superb Combi PHEV for more.

Other than that trio, you'll be looking at SUVs in reality, unless you fancy moving to a fully electric car.

Come back to us if you want help narrowing things down further.

Hi Barry,

Assuming you might like to use the rear seats, the BYD is the least spacious option of the three as its boot is much smaller. It holds up to 425 litres with its rear seat in place, while the Santa Fe PHEV manages 621 litres in five-seat mode (it's a seven-seater in which you can easily fold down the third row of seats).

The Kodiaq PHEV (assuming you're only looking at the plug-in-hybrid versions of each car mentioned) is a strict five-seater, but it comes with the largest space behind at 725 litres. If can be had in seven-seat guise with a simple petrol or diesel engine if you need the flexibility of the interior.

One major extra bonus of the Santa Fe is that its tailgate reveals the widest opening of the three, though really, the Skoda is likely to fit the bill as well. Their load sill heights are about the same distance from the ground at in and around 760mm.

Hi John,

I'm afraid not. Skoda Ireland confirmed as much to us. Demand is low and the VRT would make it prohibitively expensive.

Hi Tomas,

The belt in that engine is 'dry'.

Thanks for the kind words, Parick.

Actually, Skoda already offers an optional USB port in the rear-view mirrors of some of its models.

A few brands have a camera system integrated as well, with footage that can be used afterwards. Tesla is particularly strong on this, but Mercedes, BMW and MINI also have the functionality available, while the previous-generation Citroen C3 also came with something similar.
