Estate vs SUV: Which Makes the Better Used Family Car?
SUVs might rule the school run, but does your family really need a big, tall car? We compare used estates and SUVs on boot space, rear seat room, running costs and value.

Take a look around any school car park and you'll see SUVs everywhere. They've become the default family car in the UK, and more than half of all new car models on sale in 2025 were SUVs, according to research by CarGurus. But that doesn't necessarily mean an SUV is the best choice for your family.
The humble estate car has been quietly doing the family car job for decades, and in many ways, it still does it better. Here, we compare used estates and SUVs on boot space, rear seat room, running costs and value, to help you decide whether you really need an SUV, or whether an estate would suit you just as well. If you're new to the term, our guide to what an SUV is explains what makes an SUV an SUV.
Estate vs SUV: what's the difference?
An estate is essentially a regular hatchback or saloon with the roof stretched back over a longer, squarer boot. An SUV, which stands for sport utility vehicle, sits higher off the ground and has a taller body, so you get a raised driving position and a more rugged look. Despite the tough image, most SUVs are front-wheel drive and won't go anywhere an ordinary car can't.
To make this a fair fight, we've mostly compared two cars from the same brand: the Skoda Octavia Estate and the Skoda Karoq SUV. They're a similar size, share the same 148bhp 1.5-litre petrol engine and cost similar amounts new, so the differences come down mainly to their shape.
Boot space: estates usually win
You might assume that a taller car has a bigger boot, but that's often not the case. The Octavia Estate has a 640-litre boot with the rear seats in place, while the Karoq has 521 litres, which is nearly 120 litres less. Fold the rear seats and it's 1,700 litres for the Octavia, against 1,630 litres for the Karoq. The estate's boot is also long and flat, which is ideal for a pushchair, a big dog crate or a trip to the tip.
An estate's lower boot floor makes it easier to lift in heavy shopping, too, and older dogs will thank you for not having to jump up so high.
It's a different story with the biggest SUVs, though. The latest Skoda Kodiaq has a vast 910-litre boot in five-seat form, which beats the 690 litres in the current Skoda Superb Estate, and it's available with seven seats, which very few estates can offer. So, if you regularly need room for more than five, a large SUV is hard to beat, and our seven-seater listings have plenty of choice.
Rear seat room and fitting child seats
In the back, there's less to choose between them than you might think. Both the Octavia Estate and Karoq have plenty of legroom for adults, although the Karoq's taller roof gives a little more headroom, and its higher seats give children a better view out, which can make long journeys less of a chore.
Where SUVs really score is getting children in and out. Because the seats are higher up, you don't have to stoop as much to lift a toddler into a child seat or click an Isofix base into place, and your back will appreciate it. Higher-spec Karoqs also come with VarioFlex rear seats, which slide individually and can be taken out altogether for maximum space. Whichever car you're considering, take your child seats along when you view it to check they fit, and the GOV.UK rules on child car seats explain which seat your child needs.
Running costs: estates are cheaper to fuel
Because estates are lower and more streamlined, they generally use less fuel than an SUV with the same engine. Compare a 2024 Octavia Estate SE L with the 148bhp 1.5-litre petrol engine and automatic gearbox with a Karoq SE L with the same power, and the Octavia's official figure is 55.4mpg, against 46.4mpg for the Karoq. To be fair, the Octavia's engine also gets mild-hybrid assistance, but its sleeker shape makes a big difference, too.
Over 10,000 miles, those official figures mean the Octavia would use around 160 fewer litres of petrol. At 135p a litre, that's a saving of more than £200 a year, and the Octavia's CO2 emissions are 23g/km lower, too.
Tyres are another cost that's easy to overlook. SUVs often come on bigger wheels, and the Karoq SE L has 18-inch alloys, compared with 17-inch wheels on the Octavia SE L. Bigger tyres usually cost more to replace. Insurance and road tax are much the same, though. Both cars sit in insurance group 19 or 20, and any car registered since April 2017 that cost less than £40,000 new pays the standard rate of road tax, whatever its shape, as the GOV.UK vehicle tax rate tables show.
If you cover lots of motorway miles, a diesel estate is about as economical as family cars get, as our guide to petrol vs diesel explains.
Used prices and value
SUVs are in such high demand that they tend to hold their value well. That's good news when you come to sell, but it means you'll usually pay more to buy one used. Estates, on the other hand, can be a real bargain.
As a rough guide, a 2023 Skoda Karoq SE L petrol with around 25,000 miles costs about £18,000 on Cazoo, while 2023 Octavia Estates start from around £14,500, so the estate gives you a bigger boot for less money. It's a similar story further up the range. Previous-generation Skoda Superb Estates, sold from 2015 to 2024, start from around £7,000, and that buys you enormous rear legroom and a 660-litre boot.

Driving and comfort
Estates tend to feel more composed along a twisty country road. Their lower centre of gravity means they lean less in corners, and they're often quieter at motorway speeds, as there's less body for the wind to push against.
SUVs, on the other hand, give you a high driving position that many drivers love, with a better view of the road ahead and over hedges on country lanes. They're also easier to climb in and out of, which suits anyone with a bad back, or older relatives who travel with you.
Does a family really need a big SUV?
For most families, the honest answer is no. A family of four with a dog, a pushchair and a holiday's worth of luggage will fit into a good estate just as easily as an SUV, and often more easily. The estate will usually cost less to buy and run, too.
An SUV makes more sense if you need seven seats, find it hard to bend down to fit child seats, regularly drive on muddy tracks or simply prefer a higher driving position. And there's nothing wrong with choosing one because you like the way it looks, as long as you know you'll pay a little more for the privilege. If you're still undecided, our round-up of the best used cars includes our favourite estates and SUVs, and our SEAT Ateca vs Skoda Karoq comparison looks at two popular family SUVs in more detail.
Frequently asked questions
Is an estate or an SUV more practical?
For boot space, an estate usually wins. A Skoda Octavia Estate has 640 litres, compared with 521 litres in the similarly sized Skoda Karoq SUV. SUVs are easier to get in and out of, though, and the biggest ones offer seven seats.
Are SUVs safer than estates?
Not necessarily. Safety depends on the individual car rather than its body style, so it's worth checking each car's Euro NCAP rating. Both the Octavia and the Karoq scored the maximum five stars when they were tested.
Do estates hold their value as well as SUVs?
Generally not, because more people want SUVs. That makes estates a smart buy on the used market, as you'll often get a newer or better-equipped car for the same money.
