Its "Top-Rated Dealer" badges run on verified buyer reviews, but the same dealers pay Carfax thousands a month for listings and subscriptions, and that commercial tie isn't shown next to the ratings.
What it's really for A used-car data and listings business; the dealer ratings come from Carfax-sourced buyers.
What our grade covers The grade on this page is about its 'Top-Rated Dealer' awards from buyer reviews, not everything the site does.
Medium Scoring Confidence Mostly sourced, but a detail or two still needs a primary source, so the grade could shift slightly.
Auto dealers pay Carfax the most (reports, subscriptions of roughly $999+/month, and listing add-ons of roughly $899/month); by Carfax's own disclosure the Top-Rated award is earned "strictly through verified feedback," but marketplace listing visibility is a paid advertising product.

- What it costs you
- Free to read The reviews are free to read.
- How they make money
- Carfax makes money selling vehicle history reports to consumers and dealers, dealer software subscriptions, and paid listing/advertising placement for dealers on Carfax.com.
- What they do
- Carfax runs a used-car listings marketplace and a dealer ratings system, awarding annual "Top-Rated Dealer" recognition based on verified consumer reviews from buyers who shopped through Carfax.
- What to watch for
- Carfax doesn't show, next to a dealer's rating or listing, that the dealer pays Carfax for reports, software subscriptions, and advertising, so you can't easily tell a customer-driven rating apart from a paying-customer relationship.

How the grade was reached
Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.
What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.
Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?
Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?
How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
