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.

Quick Takeaways

  • AutoNation sits at the top by revenue and total locations, operating more than 300 stores across 18 states.
  • CarMax leads the used‑car segment, selling over 800,000 used vehicles in 2024.
  • Group 1 Automotive, Penske Automotive Group, Lithia Motors, and Sonic Automotive round out the top five.
  • Size can be measured by revenue, dealership count, or units sold - each tells a slightly different story.
  • Digital retail tools are reshaping the traditional brick‑and‑mortar model, so “largest” may shift in the next few years.

How We Define "Largest"

Before naming a winner we need a definition. Analysts typically look at three metrics:

  1. Revenue - total earnings from new and used vehicle sales, service, parts, and financing.
  2. Dealership count - the number of physical locations a chain operates.
  3. Units sold - the sum of new and used vehicles moved in a fiscal year.

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: The Current Leader

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.

Other Major Chains: A Comparative Snapshot

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.

Top 5 US Car Dealership Chains (2024)
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.

Why the Rankings Matter to Car Buyers

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:

  • Lower financing rates thanks to in‑house loan departments.
  • Consistent after‑sale service standards across all locations.
  • More robust online tools - inventory searches, price‑match guarantees, and virtual tours.

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.

Emerging Trends That Could Shift the Leaderboard

Even the current "largest" chain can be dethroned if market dynamics change. Two forces are especially visible:

  1. Digital retail transformation - Companies like Carvana and Vroom are proving that a fully online buying experience can move high volumes without a traditional lot. AutoNation has responded with its "AutoNation Direct" platform, but competitors are catching up quickly.
  2. Growth of the used‑car market - Economic pressures keep demand for certified pre‑owned vehicles high. Chains that double‑down on used‑car inventory, like CarMax, could outpace traditional new‑car dealers in units sold.

Watch the 2025 earnings season - we may see a reshuffle in the top five as digital‑first retailers gain market share.

How to Verify a Dealership’s Size and Reach

If you want to confirm a dealer’s scale before walking in, follow these steps:

  1. Check the company’s annual report or SEC filings - revenue and location counts are disclosed.
  2. Visit the official website; most chains publish a "Our Locations" map.
  3. Search industry rankings from sources like J.D. Power, Automotive News, and the National Automobile Dealers Association (NADA).
  4. Look for third‑party reviews that mention service consistency across different states - a hallmark of large, well‑managed groups.

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.

Frequently Asked Questions

Which dealership chain has the most locations in the US?

AutoNation operates the largest network, with roughly 300 stores spread across 18 states as of 2024.

Is the "largest" dealership always the best choice for buyers?

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.

How does CarMax compare to AutoNation in terms of size?

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.

Do digital‑only retailers affect the ranking of traditional dealership chains?

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.

Where can I find the most recent data on US dealership chains?

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.
