We're mapping the car rental market. The same car isn't the same size twice.
Book the same car, in the same country, from different rental companies, and they often won't agree on what size it is. Same car, different size class, depending on who you book with. We're normalizing the whole market to one honest identity per car, and the inconsistency is everywhere. Pick a car and watch it happen.

Why it matters
The size label isn't a fact. It isn't even consistent.
The size class decides which car actually shows up at the counter, and whether two listings can even be compared. You'd expect it to be standardized. It isn't. When the same car is Compact at one company and Standard at another, three things follow.
There's a real cost buried in all this inconsistency, and it's measurable, booking by booking. That's a finding for another day. This one is simpler: the label you're trusting isn't standardized, and we can show you exactly where it breaks.
It gets stranger
One company can't even agree with itself across borders.
This isn't different companies disagreeing. It's a single rental company filing the exact same car under a different size, country to country.

rental listings shows a car that's no longer built.
31 of 33 models we verified as out of production are still shown as example cars for rent. Still listed isn't the same as still available.
Where this goes
We're not pointing fingers. We're fixing the map.
The industry isn't dishonest, it's unmanaged. There's no shared referee for what a car actually is, so the same vehicle drifts across labels and borders. We're building that reference from our own data, normalized across the market and updated as it grows. This isn't a one-off illustration. We're going to keep showing exactly what's inconsistent, finding after finding, and help fix it. We're not slowing down.
We're doing this to make rental clearer for everyone in it: customers, brokers, intermediaries, and the rental companies themselves. Better data, fewer disputes, fairer pricing, more trust. Not just for us. For the whole industry.
Get the next finding. A lot more is coming.
Pricing, cross-border differences, the downgrade story, and what a customer-first approach could look like. Occasional notes, no noise, no supplier bashing.
We send to this list ourselves. We don't sell it, and we don't share it.
