CarMax’s 30th birthday party was a real bell-ringer.

The nation’s largest used-car retailer celebrated its 30 years in business by ringing the closing bell Tuesday at the New York Stock Exchange. President and CEO Bill Nash and vice president of corporate social responsibility Laura Donahue — a founding CarMax associate — did the honors, accompanied by other founding associates and members of CarMax’s senior leadership team.

CarMax opened its first store Sept. 18, 1993, Since then, it has sold more than 11 million cars at retail and more than 7 million at auction. The company currently operates more than 240 stores in 41 states and employs more than 30,000 people.

CarMax Auto Finance, which provides financing solely to customers buying retail vehicles from CarMax, has grown into one of America’s largest providers of used vehicle financing.

“Not many companies have the opportunity to revolutionize an industry twice,” said Nash, who has been with the company for more than 25 years. “We are proud to have reshaped the used car industry starting in 1993 through no-haggle pricing and bringing honesty and integrity to every interaction.

“These values continue to guide us, and we are excited to reshape the industry again by offering a uniquely personalized car-buying experience that enables customers to do as much or as little online and in-store as they want.”
