How Does CarGurus Work?

CarGurus is a car-shopping marketplace first and a review platform second, and understanding that order explains most of how it behaves. Shoppers search inventory across many dealers at once, and CarGurus itself labels each listing with a price-based "Deal Rating" — Great, Good, Fair, or High/Overpriced — based on how that vehicle is priced against comparable ones nearby. Sitting right next to that price label, on the same results page, is something entirely separate: a dealer-level star rating built from buyer reviews.

Those two systems answer different questions for a shopper. Deal Rating answers "is this a fair price," and it’s CarGurus’ own analysis, not something a dealer can request changes to. The star rating answers "can I trust this dealer," and it’s built the same way review ratings get built anywhere — real buyers leaving real feedback after a real purchase.

Who uses CarGurus, and on which side

On the consumer side, shoppers use CarGurus to compare inventory across many dealers in a metro area simultaneously, filtering by price, distance, and Deal Rating before ever calling anyone. On the dealer side, used and new-car dealerships list inventory and manage a single marketplace profile that every one of their listings links back to — the star rating isn’t per-car, it’s per-dealership.

That dealer-level structure matters: a review left about one car purchase, one negotiation, or one pickup experience affects every single listing that dealership has posted, not just the vehicle the reviewer bought.

How reviews get submitted and tied to real buyers

Buyers leave reviews of the dealership directly through CarGurus after a purchase, covering the parts of the transaction that don’t show up in a price comparison — the negotiation, the paperwork, how pickup or delivery went. Reviews tied to a verifiable purchase read as more credible to shoppers doing due diligence than generic feedback, which is why review requests should always target people who actually bought a car, not just those who inquired or test-drove.

The star rating that results rolls up across the dealership’s entire inventory and appears on every listing card in search results — the same page a shopper is using to compare several similarly priced dealers side by side.

Requesting reviews the compliant way

CarGurus, like every legitimate review platform, has clear rules about how dealers can solicit reviews.

• Invite every real, recent buyer at delivery — not a filtered list of the customers you’re confident will leave five stars.
• Never offer a discount, gift, or any other incentive tied to leaving a review.
• Don’t ask shoppers who only inquired or test-drove without buying; the request should go to actual buyers.
• Send the request close to delivery, when the experience is freshest, and follow up once for buyers who don’t respond.

How CarGurus moderates and handles fraud

CarGurus monitors for the review-manipulation patterns any marketplace has to watch for — sudden spikes, reviews with no tie to a verifiable transaction, and coordinated or templated content. It removes reviews that violate its content guidelines. It does not remove a review simply because a dealership disagrees with the buyer’s account of the sale, and because the rating is dealer-level and highly visible, an inconsistent or clearly manufactured pattern tends to get noticed by shoppers as well as by CarGurus itself.

The practical implication for a dealership is that price competitiveness and reputation are two separate levers on CarGurus, and both need active attention. A dealer can carry Great Deal pricing across its whole inventory and still lose the inquiry to a lower-priced competitor with a noticeably stronger star rating — price gets the click, reputation gets the call.
