Trying to figure out who runs the biggest car dealership in the US? The answer depends on what “biggest” actually means to you. Acreage? Sales volume? Corporate revenue? Each metric reveals a different winner. This guide breaks down every category so you can see exactly who’s dominating American automotive retail right now. Stick around — the numbers are genuinely jaw-dropping.
What “Biggest” Actually Means in Car Dealerships
Size in automotive retail isn’t one-dimensional. A dealership can be massive in three distinct ways:
- Physical footprint — acres of land, square footage of showrooms
- Sales volume — how many cars roll off the lot each month
- Corporate revenue — total earnings across hundreds of locations
Each category has a different champion. Let’s meet them all.
The Biggest Car Dealership in the US by Physical Size
Cerritos Auto Square: The 125-Acre Heavyweight
When it comes to sheer land mass, Cerritos Auto Square in Cerritos, California takes the crown. Spanning approximately 125 acres just west of Interstate 605, this automotive hub houses 24 distinct dealerships and around 800,000 square feet of enclosed floor space.
That’s not a dealership. That’s basically a small city dedicated entirely to selling cars.
The story started in 1979 when the Cerritos Redevelopment Agency transformed Studebaker Road into what would become the world’s largest automotive retail hub. By 1988, the city had poured over a million dollars into landscaped medians, decorative streetlights, and — yes — rocky waterfalls. Because apparently buying a minivan should feel like a spa day.
The economic impact on Cerritos is staggering:
- Historically generates roughly half of all retail sales in the entire city
- Produces approximately $12 million in annual sales tax revenue
- Sold over 48,000 vehicles in a single year, surpassing $1 billion in cumulative sales
With 29 import and domestic brands under one roof, Southern California buyers can comparison-shop across virtually every major automaker without moving their car.
Ricart Mega Mall: America’s Largest Single-Owner Campus
While Cerritos is technically a collection of separately owned dealerships within a city-planned zone, Ricart Automotive in Columbus, Ohio holds the title of the largest single-point, single-owner auto mall in the nation.
Covering 67 acres, this third-generation family business has been expanding since 1953. The campus stacks seven new-car brands — Ford, Hyundai, Kia, Nissan, Buick, Chevrolet, GMC, and Genesis — alongside a massive pre-owned showroom and the oldest continuous motorcycle dealership in the country. All on one property.
When inventory gets tight, Ricart doesn’t just look locally. The operation famously expanded its pre-owned vehicle sourcing radius from 200 miles to a full 400-mile search net to keep its 67-acre lot stocked — a move that shows exactly what it takes to feed a dealership this size.
Longo Toyota: The World’s Largest Single-Franchise Dealership
For a single-brand operation, nothing beats Longo Toyota in El Monte, California. Sitting on over 50 acres, it’s the largest individual automotive dealership facility in the world.
Founded in 1967 by Dominic Longo, the store sold 469 vehicles in its very first year and immediately became the highest-volume Toyota dealer in the country — a title it’s held for over five decades. After Penske Motor Group acquired it following Dominic’s passing in 1985, the campus grew from 21 acres to its current 50-acre setup.
What makes Longo Toyota genuinely unique is its on-site ecosystem. The campus includes:
- A Starbucks and Subway for waiting customers
- A Verizon Wireless store
- An Automobile Club of Southern California branch
- Multiple rental car offices for service customers
It’s less of a dealership, more of a lifestyle campus that happens to sell Corollas.
Galpin Ford: Where Dealerships Become Destinations
Galpin Ford in North Hills, California pioneered the idea that a dealership should be a destination. The three-level, 200,000-square-foot showroom features a 1,000-gallon saltwater aquarium, specialized boutiques, and the “Horseless Carriage” — widely considered the first full-service restaurant ever built inside a car dealership, introduced back in 1966.
In 2015, Galpin added a 27-acre complex with a 1.6-mile driver development track and a driving simulator laboratory. With inventory routinely exceeding 1,300 vehicles, Galpin serves everyone from commercial fleet buyers to off-road enthusiasts heading to the Angeles National Forest.
Physical Giants at a Glance
| Dealership | Location | Scale | Defining Feature |
|---|---|---|---|
| Cerritos Auto Square | Cerritos, CA | ~125 acres | 24 dealerships, 800,000 sq ft municipal mall |
| Ricart Mega Mall | Columbus, OH | ~67 acres | Largest single-point, single-owner campus |
| Longo Toyota | El Monte, CA | ~50 acres | Largest single-franchise facility worldwide |
| Roseville Auto Mall | Roseville, CA | 955-acre master plan | 17 dealerships in regional commercial zone |

The Biggest Car Dealership in the US by Sales Volume
Brandon Ford: The F-Series King of Tampa
Physical size is impressive. But moving metal is a different game entirely. Brandon Ford in Tampa, Florida consistently ranks as the world’s largest volume Ford dealership, with an especially dominant grip on F-Series truck sales.
The numbers are staggering. Brandon Ford routinely carries:
- Nearly 1,000 new Ford F-150 models
- Over 350 new Super Duty trucks
- 200 Escapes, plus 150 units each of the Ranger, Explorer, and Mustang
By stocking every trim level from base work trucks to luxury King Ranch and Platinum configurations, Brandon Ford captures buyers who want their vehicle today — not in six weeks. This high-velocity approach runs on thinner per-vehicle margins, but aggressive factory volume bonuses and rapid inventory turns drive overall profitability.
The results? Brandon Ford has earned Ford’s prestigious President’s Award for over two decades consecutively, plus the Ford Triple Crown. They also hold the record for selling more certified pre-owned vehicles in a single month than any other Ford dealer in history.
Dave Smith Motors: Rural Idaho’s Unlikely Giant
Here’s a story that defies every rule of retail geography. Dave Smith Motors sits in Kellogg, Idaho — a town of roughly 2,400 people — and grew into the largest Dodge, Chrysler, Jeep, and Ram dealer in the world, plus the largest GM dealer in the Pacific Northwest.
How? By embracing internet sales before anyone else in the industry even knew what a website was.
In the early 1990s, the dealership built proprietary customer management software — eventually called “Lead Rocket” — that turned geographic isolation into a non-issue. Today, Dave Smith carries roughly 2,000 units on expanded lots scattered across 37 acres, and moves over 1,000 vehicles per month. Buyers fly in from all 50 states, drawn by transparent no-haggle pricing and inventory depth that most metro dealerships can’t match.
Dave Smith Motors proved one thing definitively: if your pricing is honest and your inventory is deep, customers will find you — even in rural Idaho.
The Biggest Car Dealership Groups in the US by Revenue
While individual locations like Brandon Ford grab headlines, the true corporate giants operate on an entirely different scale. The auto dealership consolidation trend has accelerated dramatically. By 2024, the top 10 dealership groups controlled a record 9.3% of roughly 17,000 US dealerships, while the top 150 groups accounted for over 24% of total retail sales.
Lithia Motors: The Current Revenue King
Lithia Motors has executed one of the most aggressive acquisition strategies in automotive retail history, reporting trailing twelve-month revenues exceeding $37 billion in 2026. Their growth formula is straightforward: buy large regional groups fast, deploy their proprietary digital retail platform Driveway, and expand globally.
Recent acquisitions include the Suburban Collection in Michigan, the Priority Auto Group in Virginia, and international moves like acquiring the Jardine Motors Group in the UK for roughly $385 million. Lithia has also invested in fleet management by acquiring a stake in vehicle fleet manager Wheels — pushing well beyond traditional dealership revenue streams.
Penske Automotive: The Precision Play
Penske Automotive Group runs a tighter, more focused operation. With revenues exceeding $32 billion, Penske prioritizes premium luxury brands and heavy-duty commercial trucks over pure domestic volume. Their international footprint spans the UK, Germany, Italy, and Australia — acting as a natural hedge against US market volatility.
Penske also maintains a notably conservative balance sheet, operating with a net debt-to-earnings ratio of just 1.2. When interest rates spike and highly leveraged competitors feel the pressure, Penske stays relatively insulated. It’s the financial discipline that separates a sustainable empire from an overleveraged one.
AutoNation: The Brand Builder
Despite trailing Lithia in revenue at approximately $27 billion, AutoNation has built the most recognizable brand in automotive retail. Their strategy focuses on brand extensions — including a standalone used-vehicle chain called AutoNation USA and a network of proprietary collision centers.
AutoNation has also made a forward-looking partnership with Waymo, serving as the primary maintenance provider for their autonomous vehicle fleet. It’s a deliberate bet that their service infrastructure will matter just as much in a self-driving future as it does today.
Corporate Giants Compared
| Group | Revenue | Strategic Focus | Global Presence |
|---|---|---|---|
| Lithia Motors | ~$37.72B | Aggressive M&A, digital retail | US, Canada, UK |
| Penske Automotive | ~$32.06B | Luxury brands, commercial trucks | US, UK, Germany, Australia |
| AutoNation | ~$27.49B | Omni-channel, used car stores | Primarily US |
| Group 1 Automotive | ~$22.47B | Multi-brand new and used | US, UK, Brazil |
| Asbury Automotive | ~$17.96B | High-value acquisitions, proprietary software | Primarily US |
The Used Car Market’s Biggest Player: CarMax
The new-car world isn’t the only arena where giants operate. CarMax dominates used-car retail with over $25 billion in revenue across more than 150 locations nationwide.
CarMax built its dominance on a single insight: buyers hate negotiating. Their strict no-haggle pricing model changed consumer expectations industry-wide. Behind the scenes, a sophisticated data platform tracks historical sales, local demand patterns, and depreciation curves to price every vehicle dynamically. Their national scale also lets them practice spatial arbitrage — buying undervalued inventory in one market and shipping it to regions where buyers pay a premium.
Niche players are also making noise. AutoSavvy has grown into a national force by exclusively selling branded-title vehicles — rebuilt insurance write-offs — at significant discounts to price-conscious buyers. Meanwhile, Canada’s H Grégoire Group recently invested $55 million into a Houston facility specifically designed to become the largest used car dealership in Texas by inventory volume.
What’s Driving Dealership Consolidation Right Now
The buy/sell market hit an all-time record in the first half of 2024, nearly double the pre-pandemic average. Several forces are pushing independent owners toward the exit:
Rising floorplan costs. Dealerships borrow money against every vehicle sitting on their lot. When interest rates rise, holding unsold inventory gets expensive fast. Smaller independents feel this pain far more acutely than cash-rich corporate groups.
Technology investment demands. Building a competitive digital retail platform costs millions. Lithia’s Driveway and Asbury’s Clicklane allow customers to complete an entire purchase online. Independent dealers simply can’t afford to build comparable systems.
EV infrastructure requirements. Transitioning to service electric vehicles means upgrading electrical grids, installing commercial charging stations, and retraining every technician. The capital requirements are steep, and many family-owned shops are choosing to sell rather than absorb the cost.
Generational succession. Many longtime family dealership owners lack successors willing to take on an increasingly complex business. Selling to a corporate group at record valuations beats leaving the business to atrophy.
The Asbury Automotive acquisition of Larry H. Miller Dealerships for $5.7 billion demonstrated the scale of capital now flowing through this market. Even Warren Buffett recognized the opportunity — Berkshire Hathaway entered automotive retail through the acquisition of the Van Tuyl Group, which generated roughly $9 billion in annual revenue across 72 dealerships, signaling to Wall Street that car dealerships are fundamentally sound long-term investments.
The Future: Mega-Dealerships as Mobility Hubs
The biggest car dealerships in the US aren’t just getting larger — they’re changing what a dealership fundamentally is. The physical showroom is merging with digital retail, service centers are expanding to capture recurring revenue, and forward-thinking groups are positioning themselves to service autonomous vehicle fleets.
AutoNation’s partnership with Waymo’s self-driving fleet is an early example of this pivot. A dealership’s real value in a future with fewer individual car owners might be its ability to keep entire fleets clean, charged, and running — not just selling vehicles to individual buyers.
The definition of the biggest car dealership in the US will keep evolving. But right now, whether you measure it by acres, sales volume, or corporate revenue, the entities winning this race share one thing: the willingness to invest heavily, move fast, and think well beyond the traditional lot.
