CARMAX LAUNCHES CUSTOMER RATINGS AND REVIEWS ON CARMAX.COM

RICHMOND, VA,– April 23, 2007 –   CarMax, Inc. (NYSE: KMX), the nation’s largest retailer of used vehicles, announced today the addition of a customer ratings and reviews feature on carmax.com, which will help consumers make more informed car-buying decisions. By logging onto www.carmax.com/reviews, consumers can read and write reviews on specific makes and models included in CarMax’s nationwide inventory.

"We are committed to providing our customers with an unbeatable car-buying experience, both in-store and online," said Tom Folliard, president and chief executive officer of CarMax. "Providing our customers with the opportunity to share their experiences will offer valuable insights into automobile opinions from a consumer’s point of view."

CarMax’s primary goal is to make car buying easier for its customers. Providing customers with the ability to read and write reviews is just another example of CarMax’s dedication to exceeding consumer needs. In addition to offering reviews, the new service provides a five-star rating system that allows consumers to rate vehicles on attributes, such as comfort, performance, appearance, and quality.

"Word of mouth is a driving force when shopping for a car," said Brett Hurt, Bazaarvoice’s founder and chief executive officer. "The Bazaarvoice hosted customer ratings and reviews service enables CarMax customers to more effectively communicate their opinions on specific makes and models. The addition of a five-star rating system allows shoppers to quickly visualize how the collective marketplace rates a certain vehicle."

CarMax offers consumers a no-hassle, no-haggle car-buying experience and a broad selection of high-quality used vehicles. CarMax guarantees the quality of the cars sold, does not sell flood or frame-damaged vehicles, and guarantees a clean title and accurate odometer readings on its cars. All vehicles are thoroughly inspected and reconditioned, and CarMax offers a five-day, money-back guarantee and a limited 30-day warranty (60-day in Connecticut).

Online shoppers can use the carmax.com website to search the company’s inventory of more than 25,000 used and new cars. The website showcases each vehicle with multiple photos, the "no haggle" price, and information on features, options, and fuel economy. In fiscal year 2007, carmax.com averaged more than four million visits per month.
