Buying a family car, a guide for parents

For most families, a car isn’t a flashy extra. It’s essential. It gets you from A to B, copes with school runs and weekends away, and somehow ends up carrying half your house every time you leave the driveway. Anyone who’s tried to juggle prams, bags and snacks on a crowded train knows why having the right car matters.

A car is also a serious investment. When you’re spending that much money, you want something that will last, suit your family now and still work a few years down the line. That’s easier said than done if you’re not a car expert.

So we’ve done the legwork, reading through family car threads on the Mumsnet forums and pulling together expert advice and insights from Autotrader - the UK's largest and most trusted car marketplace - to help you work out what actually matters. From safety and space to budgets and car types, here’s how to choose a family car without losing your mind.

What makes a good family car?

A good family car depends on your family. There’s no one-size-fits-all answer, but a two-seat sports car probably isn’t going to cut it, however nice it looks on the drive.

Safety is usually top of the list. Many parents look for a car with a five-star Euro NCAP rating, which is the standard crash safety score for cars sold in Europe. This takes into account adult and child protection, as well as safety assist features.

Size and shape matter more than you might think. Slimmer models can look smart, but they may leave you short on legroom or boot space. If you regularly travel with kids, bags and pushchairs, you’ll appreciate extra room, especially on longer trips when it feels like you’re packing everything but the kitchen sink.

Seats and access are also worth checking properly. Some cars technically seat three in the back, but the middle seat can be very narrow. That might work for a small child, but it’s less practical as they grow, or if you’re trying to squeeze in a grandparent. With seven- or eight-seater cars, it’s also worth checking how easy it is to get into the back row, particularly for older passengers.

If you have babies or toddlers, check how many seats have ISOFIX points so child seats can be fitted easily. Folding rear seats are another practical win, especially when you need to transport bulky items.

Storage makes a big difference to day-to-day life. A decent-sized boot is important, but smaller details matter too, like door pockets and compartments for toys, water bottles and snacks.

Features such as parking sensors or a reversing camera might sound like luxuries, but many parents find them genuinely useful. They can also help when it comes to resale value.

Finally, think about the interior. Darker fabrics tend to be more forgiving in family cars. And yes, there will be stains.

There’s no one-size-fits-all answer to the best family car - decide what’s best for you

What are the typical models for family cars?

Hatchback

Hatchbacks are compact and easy to drive, with a boot that opens upwards and seats that usually fold flat. They can work well for smaller families or city driving.

In fact an electric hatchback picked up the best family car award in Autotrader’s prestigious 2025 New Car Awards voted for by 225,000 people. The BMW i4 scooped the prize for its smooth handling, comfortable seats, handy charging ports and thoughtful storage options. The BMW iX3 and the Volvo XC60 were deserving runners up. 

Estate 

Estate cars offer more boot space than hatchbacks, making them a good choice if you regularly travel with luggage, pushchairs or pets.

SUV or crossover

SUVs and crossovers sit higher off the road, which many parents like. They usually offer more legroom and boot space, but they can be pricier to buy and run.

MPV (people carrier)

MPVs often have three rows of seats, sliding doors and plenty of headroom. They’re practical for larger families, though they’re less common than they used to be.

Saloon

Saloons have a separate boot and cabin. While boot access can be more limited than in an estate or SUV, they often offer a smooth, comfortable drive and decent fuel efficiency.

New vs used family cars

A used car can be a sensible choice, but there are a few things to think about before you buy. Used cars have had one or more previous owners and are often bought privately rather than from a dealership. They’re usually much cheaper than buying new and there’s a wider choice available.

Used doesn’t automatically mean unreliable or inefficient. While the original warranty may have expired, you can often buy a third-party warranty for peace of mind. If the car is over three years old and was registered in the UK after 2003, you can check its full MOT history online by entering the registration number on the government’s MOT check website.

If older cars make you nervous, it’s worth looking at nearly new or pre-registered cars. These are usually under a year old, with very low mileage, and are often sold at a discount compared to brand new models.

Buying new gives you access to the latest technology and safety features, but it comes with a higher price tag. While the upfront cost is more, many buyers use finance options to spread the cost, so it’s worth comparing what’s available.

Seats and access are worth checking, especially for younger family members

A step-by-step guide to buying a family car

Start with your budget. It’s easy to get distracted by shiny tech or upgraded interiors, but there’s no point buying a car you then struggle to afford to run.

Make a list of your non-negotiables. How many seats do you actually need day to day? It can be tempting to stretch your budget for a larger car to cover the occasional extra passenger, but it’s worth being honest about how often that really happens.

Think about future-proofing. If you’re planning more children, or your kids are growing fast, choose something that will still work in a few years’ time.

Get familiar with safety ratings and running costs, including fuel, insurance and road tax, to check the car fits your overall budget.

Many Mumsnet users recommend test driving before deciding. Comfort, visibility and seat quality make a big difference.

“I usually have a list of ones that meet what I need first but the one I have now I went completely off script and fell in love with the comfy seats, big cup holder, gear change, interior build quality and ride. Most cars have rubbish seats, even some supposedly well made cars feel cheap and nasty,” shares Ferretmad2.

Plenty of Mumsnet users also suggest using Autotrader to narrow down options.

“Look on Autotrader, use the filter to pick what’s important to you and see what comes up a reasonable distance from you that you can afford,” wrote BuildbyNumbere.

NotMeNoNo added: “Once you narrow it down to a couple of more specific models, use filters on Autotrader to find a few close to you to look at, and maybe book a test drive.”

When choosing between a dealer and a private seller, remember that private sales carry more risk, as sellers don’t have to declare every issue. Buying from a dealer is usually more expensive, but you have more consumer rights, including the option of a refund if something goes wrong shortly after purchase.

Should you consider an EV or hybrid car?

If you want a car that’s kinder to the environment, an electric vehicle (EV) or hybrid might be worth considering.

EVs run entirely on battery power. They’re quiet and cheap to run day to day, but they do have higher upfront costs and rely on access to charging points. Range can also be a consideration, particularly if you do a lot of long journeys.

Hybrid cars combine a petrol engine with an electric motor. They’re more fuel-efficient than traditional petrol or diesel cars and produce fewer emissions, but they still use fuel.

From 2030, all new cars sold in the UK will need to be electric or plug-in hybrid. Changes to how EVs and hybrids are taxed have sparked plenty of debate, including on Mumsnet.

One user described the situation as a “logistical nightmare”, while another argued that EV drivers should contribute to road upkeep, saying: “It’s ridiculous that EVs had no or low car tax anyway. How will any government find money to keep roads in good repair?”

As always, it’s worth weighing up the costs, practicality and infrastructure before making a decision.

The Kia Sportage is a popular option for families in the UK

Best family cars, according to Mumsnet users

When you’re choosing a car, honest, unbiased advice from real people makes all the difference. That’s why we turn to our Mumsnet community for their steer on the best family options.

Kia Sportage 

“Kias are absolutely great, we love ours.” yetanotherusername9183837

The Kia Sportage is a popular crossover SUV with a raised driving position, a good-sized boot and plenty of legroom. It’s available in petrol and hybrid versions, which helps keep running costs down.

Skoda Octavia 

“We have a Skoda Octavia. Boot the size of a football pitch. Plenty of space inside for four or even five people. Extremely fuel efficient - on a long trip on the motorway we can get 600 miles from a tank. Very reliable, cheap to run (and insure).” IdLikeToBeAFraser 

Affordable, practical and fun to drive, the Skoda Octavia is a popular choice for families. One of its standout features is its size, which translates to comfortable interiors and a spacious boot.

Honda Civic

“Have one from 2013 and it’s a good little car. Huge boot, usual Honda reliability, nice to drive. Prefer it to the Focus I had before and that was pretty good.” Lonelycrab

The Honda Civic is a reliable family hatchback, available in hybrid versions that save fuel. It’s quiet to drive and has a surprisingly large boot for its size.

Frequently asked questions

What should I look for when buying a family car?

Buying a family car involves a few key considerations. From our own research and Mumsnet users’ experiences, it’s clear that budget, safety, size and age are top of the list. Do your homework in advance and don’t shy away from a used model. Just always check its full MOT history before committing.

Should I lease, finance or buy a family car outright?

There are different payment options available to you when it comes to buying either a used or new car. According to Autotrader, if you’re able to buy a car outright, this can be a great option for several reasons. Though, if you want to spread the cost over monthly payments, you’re looking at either financing or leasing. 

Are SUVs or hatchbacks better for families?

There’s no one-size-fits-all answer, but both SUVs and hatchbacks offer plenty of space. If you often go on long trips or need room for luggage and gear, either option can work well.

What size boot do I need for a pushchair?

Many prams fold down easily and some travel models even fit in overhead lockers on planes. A good rule of thumb is to aim for a boot of at least 300 litres to comfortably fit a pushchair and other essentials.

Is it better to buy a new or used family car?

Both have their perks. A new car comes with no previous owners and full coverage for faults, but it’s pricier. A used car can offer great value, but make sure to check the warranty and inspect for any hidden issues.

Which cars are best for fitting three car seats?

Our Mumsnet community loves the Kia Sportage, though it’s a tight fit for three car seats. For an alternative option, Mumsnetters recommend the Dacia jogger

How do I know if a car is safe for families?

Look for a car with a five-star Euro NCAP rating, the standard for crash safety across Europe. If buying used, check the car’s registration and review its MOT history to ensure it’s been well maintained.

How much should I budget for running costs?

Your budget will depend on fuel costs, car insurance, road tax and maintenance and repairs. But if you want a reliable estimate, Autotrader has a Running Costs Tool to give you some insight before you buy.
