ISSUE 02 - OCTOBER 2026
The Family Car Edition
A baby has a remarkable ability to make your perfectly adequate car suddenly look tiny.
Car seat. ISOFIX base. Pushchair. Changing bag. Travel cot. And that's before you've even attempted your first weekend away. Where on earth did all the room go?
So it's understandable that "we probably need a bigger car" makes its way swiftly onto lots of families’ pre-baby to-do lists.
But do you?
Before you swap a perfectly good car for a shiny new SUV - and another chunky monthly payment - let's work out what you actually need.
🤔 The Big Decision
Do you actually need a bigger car?
There are some very good reasons to change cars when you're having a baby.
"It feels a bit small" isn't necessarily one of them. The real test is whether your current car can safely and practically handle your new everyday life.
Start out with four questions:
1. Does your car seat actually fit?
This is non-negotiable.
Not every child seat works equally well in every car, even if the car has ISOFIX points. Before buying either a car or car seat, check the manufacturer's compatibility information and, ideally, physically try the seat in the car.
And look at what happens to the front passenger seat once a rear-facing seat is installed. Technically fitting and comfortably fitting are two different things.
2. Can you get the pushchair in the boot?
Not "the boot looks quite big." Actually test this out.
Then imagine adding the weekly shop, changing bag, travel cot or luggage for your first weekend away. Most strollers and prams take up A LOT more space than you'd think.
Boot capacity on a spec sheet only tells you so much. Shape, loading height and wheel arches can make two similarly sized boots very different in real life. A high boot can be a real pain when trying to load and hold baby at the same time.
3. Can you comfortably get your baby in and out?
This is difficult to appreciate before you've done it hundreds of times.
A five-door car with wide-opening rear doors can be more useful than simply buying a physically bigger vehicle.
If you're test-driving a potential family car, take your actual car seat and pushchair with you.
Forget any looks you might get, this is about seeing what works best for you.
4. Are you solving today's problem - or one three years away?
One baby doesn't automatically require seven seats.
Think realistically about what your family could look like during the time you'll own the car. If another child is likely soon, rear-seat width and fitting multiple child seats might be important.
If not, paying now for space you might need someday could be an expensive way to transport fresh air.

🎯 Family Car Scorecard
Don't ask "Is it a good car?" Ask whether it's a good car for your family.
Here are 6 tests to put your current car - and anything you're considering buying.
Care-Seat Fit
Does your chosen seat fit correctly? Is there enough space left for the person sitting in front? And could the back seat accommodate another child seat if your family grows?
/5
Boot Test
Forget the quoted size for a minute. Does your actual pushchair fit easily, with useful room left over for supermarket shop, bags and everything else babies somehow require?
/5
Baby Access
Can you comfortably get your baby or infant carrier through the rear doors? Can you reach the harness without becoming a contortionist?
/5
Safety
Look beyond the badge on the bonnet. How does the car perform in independent crash testing, particularly for child occupants?
/5
Running Costs
Insurance. Fuel or charging. Tax. Tyres. Servicing.
Could your new family budget comfortably absorb all of them - not just the monthly finance payment?
/5
Environmental impact
It's natural for many people to think more keenly about the future of the planet when they are starting a new family. Will a new car be more fuel efficient? But also, producing a new car creates a great deal of carbon. Is it better in the long run, for the planet, to keep the car you have?
/5
Price
What's the deposit? What will you pay overall? And how does this compare with simply keeping your existing car?
/5
YOUR FAMILY CAR SCORE
/30
25-30 | It sounds like you've found a keeper. |
|---|---|
19-24 | Strong contender - but look closely at where you're compromising. |
13-18 | Those little annoyances could become big ones very quickly with a baby. |
12 or below | Keep looking. |
🪙 Budget Breakdown
Bigger car. Bigger costs.
Something to factor in: the price on the windscreen is only the beginning.
Changing cars can also mean:
Higher monthly finance payments
More expensive insurance
Different fuel or charging costs
Servicing, tyres and repairs
Vehicle tax
Depreciation
That last one is particularly easy to overlook.
New cars can lose value quickly. After 3 years a new car could be worth around half its original value.
So if your current car safely fits your baby, car seat and everyday kit, keeping it for another year or two could potentially save far more than finding a slightly cheaper finance deal.
Before changing cars, compare:
KEEP | CHANGE |
|---|---|
What will your current car cost you over the next 12 months? | Deposit + 12 monthly payments + insurance difference + fuel/charging + tax + expected servicing. |

⌚ Quick Win : Under 30 Minutes
Do the pushchair test.
Before you spend a penny changing cars, give your current one a proper family test.
Put your:
Pushchair
Car seat + base
Changing bag
…into the car at the same time. Then ask yourself:
Could I comfortably live with this every day?
If the answer is yes, congratulations. You may have just saved yourself several thousand pounds.
If it's a definite no, you've also learnt something valuable: exactly what your next car needs to do better.
And when you do start those test-drives? Take the same kit with you.
A 500-litre boot on a spec sheet tells you considerably less than seeing whether your pushchair actually fits in it.

Worth It ❓
WORTH THE SPEND
The car making daily family life easier.
If you’re changing anyway, prioritise the boring things.
Wide-opening rear doors. A genuinely usable boot. Easy car-seat access. Good visibility. Strong independent safety scores. Sensible running costs. You'll appreciate those far more on a wet Tuesday nursery run than another inch of touchscreen.
WORTH THE SAVE
The car you already own.
Before assuming a baby means an upgrade, test what you’ve got.
If it's safe and reliable, your car seat fits correctly and the pushchair goes in the boot without requiring a degree in spatial engineering... you might already own your ideal family car.
One Last Thing…
Having a baby creates plenty of things you genuinely need to spend money on.
Don't automatically add a new car to the list.
If your current car works, keep it. If it doesn't, don't simply buy BIGGER.
Buy the car that solves the problems you've actually identified - safely, practically and at a cost your new family budget can comfortably handle.
That's the Bump to Budget test:
Best for your budget. Best for your baby.
See you in two weeks,
