A used-car marketplace whose algorithmic "Deal Ratings" are genuinely price-vs-market, but the platform is paid for almost entirely by the dealers it ranks, and by its own disclosure paid packages and dealer reviews factor into where listings surface.
What it's really for A car marketplace; the deal rating is algorithmic, and dealers pay for listings and placement.
What our grade covers The grade on this page is about its 'Deal Rating' on car listings, not everything the site does.
High Scoring Confidence Checked against primary sources. We are confident in the facts and the grade here.
- Operating since
- 2006 (20 years) · source
- What it costs you
- Free to read The reviews are free to read.
- How they make money
- CarGurus makes money mainly from dealer subscriptions (listings packages), plus OEM advertising and dealer-to-dealer wholesale fees, so the dealers it ranks are its paying customers.
- What they do
- It lists millions of new and used cars and stamps each with a color-coded Deal Rating (Great Deal to Overpriced) by comparing the asking price to its algorithmic Instant Market Value, then connects shoppers to dealers.
- What to watch for
- The Deal Rating reflects price versus market, not the dealer's honesty or fees, and CarGurus discloses that paid "Featured" packages and dealer reviews influence where listings appear in search, so a "Great Deal" badge is not an endorsement of the seller.
- Composite score
- 2.20 / 5.00 → grade C
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.
Evidence
- CarGurus was founded in 2006 by Langley Steinert (co-founder of TripAdvisor); it is headquartered in Boston, IPO'd October 12, 2017, and trades on NASDAQ as CARG, making it an independent, founder-led public company rather than a subsidiary. Source: Wikipedia: CarGurus →
- CarGurus' own About page states its 'Best Match' sort 'showcases recommended vehicles based on a variety of factors, including shopper engagement, vehicle attributes, photos, and dealer reviews & services' — i.e., by its own disclosure, the paid services a dealer subscribes to factor into placement.

- Dealers pay for tiered listings packages, with marketplace subscriptions roughly 60% of revenue and paid 'Featured Priority+' packages providing guaranteed search-results-page exposure; CarGurus states top listings are ranked by deal value rather than payment alone.
