Secure Classic Cars: Reach out to classic car owners, car clubs, and collectors to invite them to exhibit their vehicles. Advertise through social media, classic car forums, and local car clubs to attract participants. Ensure a diverse range of cars to cater to different interests. Develop a Theme: Choose a theme that ties in with the purpose of your exhibition. It could be based on a certain era, brand, or style of classic cars. This will add coherence to the event and attract enthusiasts of that specific theme.
