Step by step

  1. 1

    Buyers can't tell good cars from lemons, so they only pay average-quality prices.

  2. 2

    History reports arrive: accidents, odometer readings, and service records become visible.

  3. 3

    Verified quality lets buyers pay more, so their willingness-to-pay line lifts.

  4. 4

    More good cars stay on the market and average quality rises. Information is the cure for unraveling.

Where this shows up

Examiners ask this as: carfax, history report, vehicle inspection, information fix, transparency.
