Collector Car Appreciation Day is observed on the second Friday of July in the United States, celebrating the significance of automotive restoration and car collecting. This day highlights the rich history of American car manufacturing and the dedication of enthusiasts who preserve it. Common activities include attending local car shows, visiting automotive museums, and admiring vintage vehicles. The day is also marked by community events rather than commercial sales, with local auto shops and restoration businesses often offering special rates on services for classic cars. Enthusiast organizations, such as the Specialty Equipment Market Association (SEMA), promote related events, while car museums may feature discounted admissions or special exhibits. Participants are encouraged to share their passion through social media, showcasing their classic cars and restoration projects.
