This sector has not been measured yet
The question set for car dealers and used cars is ready: 8 buying questions and three personas. The index runs part of the sectors each week within a fixed budget; this one is due within 4 weeks. Until then we show no numbers here — a sample leaderboard would suggest a measurement that never happened.

The 8 questions we ask
- 01“Waar koop ik het beste een betrouwbare occasion in Nederland?”
- 02“Welke occasionplatformen zijn betrouwbaar met garantie?”
- 03“Wat is een goede gezinsauto tot 15.000 euro?”
- 04“Waar verkoop ik mijn auto voor de beste prijs?”
- 05“Welke dealers geven garantie op tweedehands auto's?”
- 06“Hoe voorkom ik een auto met verzwegen schade of teruggedraaide teller?”
- 07“Welke merken zijn het betrouwbaarst volgens onderhoudscijfers?”
- 08“Is een auto kopen bij een dealer of particulier verstandiger?”
Without a brand name, in Dutch, with the Netherlands as market. The same set every week.
The personas behind the questions
- Gezin dat een betrouwbare occasion zoekt tot 15.000 euro
- Koper die twijfelt tussen dealer en particulier
- Iemand die zijn auto wil inruilen of verkopen
Personas and questions are in Dutch: the index measures the Dutch market.
Full method
How this was measured
- 01Every question goes to the engines through their API in a clean session: no account, no history, no personalisation.
- 02Brand names are extracted from each answer (text extraction). Per brand the decision layer judges whether it is a real brand in this sector, whether it is a marketplace, how it is spoken about and how prominently it appears. That certainty is shown in the table.
- 03Brands only count when the probability that they are a real brand is at least 50%. Borderline cases are left out.
- 04Share is measured over a four-week window with a 95% confidence interval. Names that turn out to be the same company are merged once the decision layer confirms it.
- 05Engines without a usable API (such as Google AI Overviews) are not in this index. Browser captures of consumer products follow once the capture service is publicly available; those will be labelled separately.
