Who else measures this,
and where they beat us.

The score controls money — bonus cheques that can run past a million dollars a year for a large store — and manufacturers typically count only the top box, so a 9 hurts. That is why the advisor asks you for a 10 before you leave, and why an industry exists to raise the number. The results are not public.

It is a genuine fixed instrument with decades of history, a response rate we will never approach, and it reaches every customer rather than the ones who volunteer. On coverage and continuity it beats Caliper outright.

Brand-level. It tells you how Toyota service ranks nationally, not how the Toyota store on your side of town behaves.

Four decades of methodological continuity, large samples, and a name the whole industry accepts as a referee.

Brand and sector level, annual, and not concerned with individual service departments.

Thirty-two years of one model, a published academic method, and cross-industry comparability none of the automotive-only measures can offer.

Reviews are unstructured, self-selected and cumulative, so a store's average reflects everyone who ever felt strongly rather than how it behaved this quarter. Dealers can pay the platform that hosts their rating.

Two decades of reviews, employee-level detail Caliper does not attempt, and near-total coverage of franchised stores.

The four categories are a real step toward a battery, but they are collected from self-selected reviewers with no proof of a visit, and the platform sells listings to the stores it rates.

It already proves the category idea works for car shoppers, and it has the audience: people rating a dealership are usually on Cars.com anyway.

A submitted lead is not a completed service visit, and the rating is a star with a comment box rather than a fixed instrument.

Tying the invitation to a real interaction is closer to verification than most review sites get, and the reach is enormous.

Open reviews, no fixed battery, no verification of a visit.

Deep consumer trust and the best car-buying editorial in the business — including the article that explains, plainly, why salespeople beg for perfect survey scores.

No verification, no fixed questions, no time series a shopper can read, and the strongest optimization pressure of any rating in the market.

Universal coverage, instant recency, and unmatched distribution. Whatever Caliper publishes, most people will still see the Google stars first.

Not built for automotive service, and unverified by design.

The recommendation filter is a serious, long-running attempt at exactly the fraud problem Caliper avoids by requiring a repair order.

Businesses pay for the tooling that generates their reviews, and the instrument is one star rating plus prose.

Transaction-verified reviews are a real feature, and Trustpilot has fought harder in public over review integrity than most of this list.

Complaint-based rather than sampled, so it measures the tail rather than the typical visit — and accreditation is a paid relationship with the rated business.

A century of standing, a real dispute-resolution process, and a complaint record that surfaces problems no satisfaction survey would ever catch.

Not a rating at all — a tool for producing them. Caliper is on the other side of that transaction.

Genuinely useful software, and its guides to dealer review platforms are among the clearest explanations of how this market works.

Sells score improvement to the rated party, which is the defect Caliper is designed around.

Consolidating a store's feedback across a dozen platforms is a real problem solved well, and dealers get value from it.

Authoritative but sparse, formatted for regulators, and effectively unsearchable for someone choosing where to book an oil change.

Legally weighty, genuinely independent, and the only source here with subpoena power behind it.

Brand and model reliability rather than the conduct of an individual service department, and thin per-store data.

Consumer Reports takes no advertising, which makes it the most genuinely independent name on this page — a standard Caliper has to live up to rather than claim.
