How these rankings work
The table sorts groups by the rooftop count recorded in this directory, from highest to lowest; groups with the same count are ordered alphabetically. A rooftop generally means an operating dealership location, but a group may report franchises, stores, acquisitions, divestitures, or international operations differently.
Methodology and date
Updated September 15, 2026. A rooftop count appears only when the underlying record supplies one; a dash means the directory does not have that fact. Revenue labels retain the reporting period available in the record. This is a directory index, not an authoritative league table: it does not infer missing figures, normalize ownership or operating scope, or convert rooftop count into a revenue or performance ranking.
Before publishing, buying, or investing on the basis of a rank, verify the current figure against the dealer group’s annual report, investor filing, or official company disclosure.
Common questions
Who owns the largest car dealership group in the United States?
The answer depends on the definition and reporting period. This directory sorts the rooftop counts recorded for each group, but each count should be checked against the group’s current primary reporting before it is used as a market-wide ranking.
What does a dealership rooftop count mean?
A rooftop generally means an operating dealership location. Definitions can differ when a group reports franchises, stores, acquisitions, divestitures, or international operations, so this table shows the recorded figure rather than treating every count as directly comparable.
How current are the dealer group facts on this page?
Revenue labels retain the reporting period available in the directory. Missing values are shown as a dash; readers should confirm material decisions with the relevant group’s most recent annual report, investor filing, or official company disclosure.
