DEI Headquarters houses the Corporate Offices of DEI, the Dale Earnhardt Foundation, Earnhardt Technologies Group, and many other arms of the DEI empire. The Dale Earnhardt Experience culminates in the Showroom and Retail Store, here in Mooresville. The Showroom was a dream of Dale and Teresa's, making the Earnhardt experience tangible to the fans. Hand-chosen items are available for purchase, from t-shirts to collectibles and beyond, many of which are not sold elsewhere. All of the pictures, awards (including all seven of Dale's NASCAR Winston Cup Series Championship Trophies) and history-making cars are on display across the Showroom's 6,000 square feet "House That Dale Built". Truly a unique experience!

Home to the Dale Earnhardt Day Fest, celebrated annually on April 29.
