Defining 'Biggest': What Makes a Dealership Giant?

It’s easy to picture the biggest car dealer as just having a massive parking lot, but there’s more to it. In the industry, “biggest” is usually about numbers—number of cars sold every year, total revenue, and the amount of real estate they own. Think of dealership giants as not just one location, but often groups managing dozens or even hundreds of showrooms across the country.

The main ways the industry measures who’s biggest are:

• Number of new and used vehicles sold: Dealers like AutoNation and Lithia Motors sell hundreds of thousands of cars every year, far more than your average local dealer.
• Total revenue: This is all the money they bring in from sales, service, parts, and even financing. Big groups rake in billions per year.
• Locations owned: The larger a group, the more stores it operates. Some mega-dealers own several brands and span coast to coast.

If you’re curious about who’s really topping the charts right now, here's a look at some real numbers:

Dealership size can also depend on brand mix—some groups sell mainstream brands, luxury cars, or both. The biggest car dealerships USA has to offer use their scale to stock more cars and offer more services, making them appealing for shoppers who want options.

But size isn’t just about bulk deals—it’s also about negotiating power. The largest dealerships can sometimes get manufacturers to offer them better pricing or bonuses that smaller lots only dream about. That’s part of why knowing who the big players are can actually help you score a deal, or at least know when you’re playing in the big leagues.

These mega-dealers almost always have the biggest selection of new and used vehicles, which means if you’re after a specific trim, color, or feature, your odds are a lot better here. And because these folks buy cars in massive volumes, they can cut deals most smaller operations just can’t touch.

But don’t just chase a logo. Each chain has its strengths—for example, AutoNation is known for online shopping and paperwork, while Lithia has a ‘Driveway’ digital retailing platform. Use those differences to your advantage when you want the best car buying tips.

What These Mega-Dealers Mean for Your Car Search

So you’re car shopping and wondering if hitting up a biggest car dealer in the country is worth your time. Here’s the deal: these mega-dealers – think AutoNation, Penske Automotive Group, and Lithia Motors – control a massive chunk of American auto sales. For example, in 2024, AutoNation alone sold over 350,000 vehicles nationwide. That kind of volume can change the game for regular buyers like us.

First, the good news. Because these places move so much inventory, they can offer you:

• Huge selection: You’ll find a bigger range of new and used vehicles, trim levels, and colors compared to what a local mom-and-pop lot can manage.
• Competitive prices and deals: Big dealers score bulk discounts from automakers, so they often run promotions or price drops smaller stores just can’t touch.
• Better trade-in offers: More wiggle room means better values for your old ride, especially when they’re trying to hit big sales targets by the end of the month or quarter.
• Robust financing options: You might get more loan or lease choices, thanks to their close ties with banks and lenders that service top car dealerships and auto sales USA giants.

But it isn’t all sunshine. Mega-dealerships have their downsides:

• Impersonal service: You might feel like just another customer number. Don’t expect the same hands-on attention you’d get at a smaller dealership.
• Upselling pressure: With massive sales teams come more "add-on" offers—think extended warranties, gap insurance, and accessories you might not really need.
• Complex negotiation: Larger stores often have more layers—managers, salespeople, even dedicated finance offices. That can make the process feel drawn out.

Curious how these mega-dealers compare to regular shops? Here’s a peek at the numbers. These three dealership groups topped U.S. car sales in 2024:

If you want selection, a biggest car dealer is hard to beat. Still, don’t let size alone decide for you. The real trick? Knowing how to work the system—using their scale to your advantage without getting lost in all the noise and hype.

Insider Tips for Dealing with Large Dealerships

Stepping into a biggest car dealer or one of the top car dealerships in the USA is a whole different deal from what you’ll find at a smaller lot. These mega dealerships move hundreds of cars a day, and their sales process is streamlined for efficiency—but that doesn’t mean you can’t slow things down and get the best outcome for yourself.

First, don’t let the size overwhelm you. Bigger lots mean more inventory and often better deals, but only if you know how to ask for them. Use their massive selection to your advantage and compare models side by side, right on the lot. Don’t be shy about asking for the out-the-door price, including all taxes and dealer fees, before you start negotiating.

One known fact: large dealerships like AutoNation and Penske Automotive Group often have set pricing strategies and online price guarantees. This means their advertised prices are usually firm—but don’t take that as the final word. You can still negotiate, especially for extras like maintenance packages, free oil changes, or better financing terms.

You’ll probably deal with multiple people—a salesperson, a sales manager, then a finance manager. Stay organized and jot down names, prices, and promises as you go. Big dealerships sometimes run special promotions or volume-based discounts to meet their huge monthly sales goals. If you visit during the last few days of the month, you may have more bargaining power because they need to hit quotas.

• Check their website for current offers and bring screenshots as proof in case the deals at the dealership look different.
• Use their service department size as leverage—ask for included services, especially if they do high volume and can afford to offer perks.
• If you’re trading in your current car, shop around or use online instant cash offers before accepting their first trade-in value.

Here’s a quick look at how the biggest names handle sales volume:

This massive scale means they move cars fast, but don’t feel pressured. Take your time, ask questions, and don’t be afraid to walk away if the deal doesn’t feel right. The next customer is right behind you, so make sure you’re getting what you want—not just what they want to sell you.

What the Future Holds for Big Auto Retailers

Things are moving fast for biggest car dealer groups and it’s not just about adding more cars to the lot. With most Americans starting their search online, mega dealers are pouring cash into digital showrooms and slick websites. AutoNation, for example, hit over 60% of used vehicle sales with at least some digital step. The push toward online sales is only getting stronger, with companies racing to make buying a car as easy as ordering sneakers.

Electric vehicles are also shaking up the game. Huge dealers have to put in serious money to retrain staff and install EV charging stations, especially since big brands like Ford and GM are demanding it. Right now, about 1 out of every 10 new cars sold in the U.S. is electric, and those numbers are ticking upward every quarter.

There’s also a trend of big dealers gobbling up smaller, family-run stores. Public groups like Lithia Motors or Penske Automotive keep buying out independent dealerships, sometimes dozens at a time. It means more locations for the giants—and fewer choices for buyers who liked the small-town, mom-and-pop feel.

Check out this quick comparison of recent stats (as of 2024):

So, what does all this mean for your next car search? Expect even slicker online buying experiences, bigger selections, and a ton of focus on electric options. But also, keep your eyes open. Sometimes, these mega dealers can get so big they lose that personal touch. If you like shopping with the top car dealerships or hunting for the best auto sales USA deals, you might find the game is shifting. For now, the giants are getting bigger and faster—just be sure you shop smart, compare offers, and don’t get swept up in the hype of a giant showroom unless it’s truly the best deal for you.
