Three independent scoring models, six dimensions each, all maintained in the open. No paid placements.
New-energy vehicles change faster than buyers can keep up. A car launched two years ago may already be obsolete in driver-assist or cabin software; a brand selling well today may struggle for parts five years out. TRUST asks: knowing what we know now, how confidently can you own this car for the next decade?
A combustion car's true cost is rarely on its windscreen sticker. Insurance, fuel, maintenance, and depreciation can outweigh the purchase price over a five-year hold. PRICE turns this scattered information into a single answer: given everything it costs to actually own, is this car fairly priced?
The most common question in the Netherlands today isn't "BMW or Mercedes" — it's "should this next car be electric?" Traditional rating systems can't compare across powertrains. SPARK puts a BYD Seal and a Toyota Camry on the same coordinates and answers, for your specific use, which makes more sense to own.
The point of CarIX is to be a system buyers can verify, not just trust. Here is how we keep the models honest.
The first business day of every month, every model is rerun with the latest data — financial filings, sales figures, fuel and insurance prices, charging-network changes, owner sentiment.
Dimension weights are adjusted every quarter based on owner feedback and market shifts. When users tell us "service network matters more than brand prestige," that's reflected in the next version.
All v 1.0 scores apply only to the Netherlands market. The same brand performs differently in different countries, so each market gets its own model: SPARK-DE, SPARK-FR, and other markets will follow.
Chinese new-energy brands have only been on NL roads for 18-24 months — TRUST data is still converging. Used-market figures depend on third-party platforms with their own biases. We surface this uncertainty rather than hide it.
No manufacturer, distributor, or dealer pays CarIX to influence a score. Sponsored content elsewhere on the site is clearly labelled and never affects model output.
Every weight adjustment, dimension addition, and data-source change is logged below with the reason. The full version history stays on this page, indefinitely.
