You probably have more Hot Wheels than you think you do.

Why parents underestimate the collection by forty to sixty percent — and why that number matters before you buy any storage at all.

The counting problem

Most parents buy storage for the cars they can see. Not for all of them.

Before you choose a garage, you need to know how many cars the child actually has. This sounds obvious. It is less straightforward than it appears. Most parents who try to estimate the collection size arrive at a number that is forty to sixty percent of the real total — because they count what is visible and forget everywhere else the cars live.

The consequence of an undercount is a storage solution that fills up immediately and produces overflow within weeks. The overflow goes back on the floor. The problem you were trying to solve has not been solved — it has just been relocated to a smaller surface area. Do the count first. Then choose the garage.

Where the cars actually are

The seven places parents forget to check before counting.

Do this before you estimate. Go through each location and add the number to a running total. The final number will surprise you.

i

The obvious place: the bedroom floor and windowsill.

The cars that are currently visible and in active rotation. Most parents start and stop here. This is the minority of the collection for any child who has been collecting for more than six months.
ii

The storage that already exists.

The bin, the box, the bag, the drawer the parent put the cars into during the last tidy-up. These are the cars that the child has mentally written off as lost. They are not lost. They are in the bin. Count them.
iii

The car seats and buggy pockets.

Every child who collects Hot Wheels has cars in the car. Usually between three and eight, distributed across door pockets, seat-back pockets, and the gap between the seat and the door. These are the cars that go everywhere and belong nowhere in particular.
iv

The bottom of the laundry basket.

Found during wash cycles, placed on top of the machine, never returned. There are usually two to five here. They survive the washing machine because they are metal and they just come out clean.
v

Grandparents’ house, cousins’ house, the childminder’s bag.

Cars travel. They leave the house in pockets and do not always come back. Some are at grandparents’. Some are with the cousins. Some are in a bag that has not been unpacked since a holiday six months ago. These count.
vi

Other rooms in the house.

The living room sofa cushions. The bathroom shelf. The kitchen windowsill. Cars migrate. A child who has been collecting for two years has cars in every room that has been played in during that time. Go through the house, not just the bedroom.
vii

The school bag, the coat pocket, the backpack.

Cars go to school. Cars go to the park. Cars live in coat pockets for entire seasons. Check every bag and every coat before you finalize the count. The number you arrive at after checking all seven locations is the actual collection size. Buy storage for that number, not the first one you thought of.

What the count tells you

Which garage the real number points to.

Once you have the honest count, the right garage is straightforward. These are the ranges.

Under 20 cars

Stage 01starting out

The obsession is new.

A full ninety-slot garage at this count is overkill. The collection has not yet proved itself. A road set, a ramp, or the Jup mini-garage with LED road is the right entry point — it matches the current scale of the collection and leaves room for the phase to either deepen into something permanent or fade without significant investment.

What we’d choose Modular road set or LED road with mini garage. Hold on the full garage until the count clears thirty.

20–50 cars

Stage 02first real collection

The 91-slot is the answer.

The collection is real and the garage is overdue. A 91-slot personalized garage will accommodate the current collection with room to grow for another one to two years. This is the sweet spot for first-garage orders — the count is high enough to justify the investment and low enough that the 91-slot will not be immediately outgrown.

What we’d choose 91-slot personalized garage. Their name on the front. Order now rather than waiting for the count to climb further.

50–90 cars

Stage 03serious collector

The 94-slot with car wash.

A 91-slot garage at this count will be full within weeks. The 94-slot Neptune gives more total capacity across different slot types — wider bays for monster trucks, showroom compartments, ramp sections — and the car wash feature matches the investment the child has already made in their collection. At fifty-plus cars, this is the correct tier.

What we’d choose Neptune 94 in the child’s preferred finish. The count justifies the upgrade.

90+ cars

Stage 04overflow problem

Display plus drawers.

At ninety-plus cars, the problem is not just display — it is overflow management. The Kronus drawer line solves both: display slots on top for the cars the child wants visible, three eleven-litre pull-out drawers below for everything else. This is the only configuration that genuinely accommodates a collection of this size without creating a second overflow problem.

What we’d choose Kronus Wine or Olive. Display on top, overflow below. The system that does not break down as the collection continues to grow.

Count the cars in the car, the coats, the cousins’ house. The number you arrive at is the collection. Buy storage for that number.

— A note from the workshop

Why the count matters more than the budget

Buying too small is more expensive than buying right.

The most common mistake we see is parents buying a storage solution that is slightly too small for the real collection — usually because they estimated instead of counted. The garage fills up immediately. The overflow returns to the floor. The parent buys a second solution six months later to handle the overflow. The total spend ends up higher than if they had bought the right-sized garage the first time.

A 91-slot garage for a collection of eighty cars will have eleven spare slots on day one. Within three months, those eleven slots will be full and the overflow problem will be back. Buy for the collection you will have in twelve months, not the one you have today. Add twenty to thirty percent to whatever the count tells you, and choose the tier that covers that number.

The opposite mistake — buying too large — is much less costly. A 94-slot garage for a collection of thirty cars means the child has sixty-four empty slots. Those slots fill up over time. The garage does not become irrelevant; it grows into the collection. The only downside of buying slightly too large is that the piece looks partially empty for a year. The downside of buying too small is that it fails immediately and needs replacing.

When in doubt, go up one tier. The collection will catch up. The garage will not shrink.

Buy for the collection in twelve months, not the collection today. The garage does not shrink. The collection always grows.

A note from the workshop

The question we ask every customer before recommending a size.

When a customer writes to ask which garage to order, the first thing we ask is: how many cars does the child actually have? Not a rough estimate — the real number, after checking the car, the coats, the bins, and the other rooms. The answer almost always comes back higher than the customer expected, and it almost always shifts the recommendation up one tier.

A customer who thought they had thirty cars does the census and finds fifty-four. The 91-slot garage they were planning to order is still the right choice — but the 94-slot is now worth considering, because the collection is already in Stage 03 territory and will hit the 91-slot ceiling within a year. The count is the most important piece of information in the decision. Everything else follows from it.

The second question we ask is how old the child is — because a ten-year-old with fifty cars is at a different stage of the collecting arc than a five-year-old with fifty cars. The ten-year-old’s collection is probably near its peak. The five-year-old’s collection is just starting. Same count, different trajectory, potentially different garage. But the count is always step one.
