Review process
Editorial review
Thresholds
Minimum sample thresholds
We publish a price range only when the underlying listing sample is large enough to be useful. Thin or incomplete samples are labeled as price data updating instead of being presented as a market estimate.
Freshness
Freshness checks
Reviewers monitor the collection date on every guide and prioritize refreshes where listings have aged, changed, or no longer reflect an active market.
Fitment
Grade verification
Seller-reported condition grades and vehicle fitment fields are normalized before publication. Records that cannot be matched confidently are excluded rather than guessed at.
Statistics
Outlier detection
Automated checks flag implausible prices, duplicate records, and values that sit far outside comparable listings. Editorial review investigates those flags before a guide is published or refreshed.
