What the NAPA Auto Parts TV commercial - When I was 18 is about.

The NAPA Auto Parts TV spot, "When I was 18," featuring Dale Earnhardt Jr., is a nostalgic tribute to the legendary driver's early career and the enduring relationship between NAPA and NASCAR.

Images of his early victories flash across the screen - a young Dale lifting a checkered flag, spraying champagne, and accepting trophies.

As he works on his car, Dale is suddenly transported to modern-day, where he's surrounded by a group of his friends and colleagues at Hendrick Motorsports. They're admiring the new parts on the car, including NAPA auto parts, which Dale credits with helping him win races throughout his career.

The commercial ends with a message from Dale Jr., thanking NAPA for their support and encouraging viewers to visit their local NAPA store for all their automotive needs.
