Which dealership chain is largest depends on how you measure. Select your preferred metric to see who leads in each category.
AutoNation leads all metrics with the largest national footprint and revenue.
When you search for "largest car dealership chain in the US", you probably expect a clear name, a quick snapshot of why it leads, and a few numbers to back it up. Below you’ll get the full picture - from how "largest" is measured to the current market leaders and what the data means for car shoppers.
Before naming a winner we need a definition. Analysts typically look at three metrics:
Each metric favours a different player. For example, CarMax’s pure‑play used‑car model pushes its sales volume higher, while AutoNation’s diversified portfolio lifts its revenue and footprint.
AutoNation is a publicly traded automotive retailer headquartered in Fort Lauderdale, Florida. Founded in 1996, the company grew through acquisitions and now runs more than 300 stores in 18 states, spanning new‑car sales, used‑car retail, service bays, and financing divisions. In 2024 AutoNation reported $27.6 billion in total revenue and sold roughly 1.2 million vehicles, making it the clear front‑runner under all three size criteria.
Key strengths include a strong online presence, a nationwide service network, and a seamless integration of digital tools like online price‑matching and at‑home test drives. Its franchise model lets each dealership retain local branding while benefitting from centralized buying power and marketing.
While AutoNation leads, four other groups command a substantial slice of the market. Below is a side‑by‑side look at the top five based on the three size metrics.
| Chain | # of Locations | 2024 Revenue (US$ bn) | Vehicles Sold (2024) | Primary Focus |
|---|---|---|---|---|
| AutoNation | ~300 | 27.6 | 1,200,000 | New & used, service, finance |
| CarMax | ~220 | 13.9 | 824,000 | Pure‑play used‑car retail |
| Group 1 Automotive | ~180 | 9.5 | 630,000 | New & used, service |
| Penske Automotive Group | ~150 | 7.8 | 540,000 | Luxury & performance brands |
| Lithia Motors | ~175 | 6.3 | 510,000 | Regional multi‑brand retail |
Each of these chains uses a slightly different franchise or corporate‑owned model. Understanding the nuances helps you gauge why one might appear larger in one metric but smaller in another.
Large dealership groups often bring economies of scale that translate into better pricing, wider inventory, and more service locations. For a shopper, this can mean:
However, size isn’t everything. Smaller, independent dealers may offer more personalized experiences or specialize in niche brands. The best approach is to match your priority (price, service, brand selection) with the strengths of the chain you’re considering.
Even the current "largest" chain can be dethroned if market dynamics change. Two forces are especially visible:
Watch the 2025 earnings season - we may see a reshuffle in the top five as digital‑first retailers gain market share.
If you want to confirm a dealer’s scale before walking in, follow these steps:
These actions give you a realistic sense of how far the chain’s footprint extends and whether its scale translates into tangible benefits for you.
AutoNation operates the largest network, with roughly 300 stores spread across 18 states as of 2024.
Not necessarily. Larger chains often offer better pricing and service consistency, but smaller independents may provide more personalized attention and niche brand expertise. Choose based on what matters most to you.
CarMax leads the pure‑used‑car segment, selling about 824,000 used vehicles in 2024, but its revenue ($13.9 bn) and total locations (~220) are lower than AutoNation’s.
Yes. As online platforms capture more sales, the revenue and unit‑sales figures of brick‑and‑mortar chains may plateau, allowing digital‑first companies to climb in market‑share rankings.
Industry reports from Automotive News, NADA, and the SEC’s 10‑K filings are the most reliable sources. They provide up‑to‑date revenue, location, and sales figures.
Whether you’re hunting for a new sedan, a certified pre‑owned SUV, or just comparing financing offers, knowing which chain sits at the top of the market gives you a solid starting point. AutoNation currently claims the title, but keep an eye on the evolving digital landscape - the next leader could be a click away.

Honestly, the data shows that AutoNation’s footprint is massive, but CarMax isn’t far behind in the used‑car arena. It’s interesting how each chain plays to its strengths – new‑car volume versus pre‑owned turnover. The diversification across finance and service really gives AutoNation an edge in overall revenue. Still, regional players can surprise you with niche expertise and personalized service.

Looks like the biggest name on the list is just a big corporate mascot. I guess size matters when you want a generic buying experience. Whatever, the smaller shops still have charm.
