Does anyone know if there is a way to see some of the vehicles such as optimus prime, bumblebee,etc at a museum or something?

There might be... Maybe like near where Bay shot the movies and stuff idk

Yes. They appeared at the last three BotCons, an annual TF Convention. And Barricade was actually sold on eBay. But i don't think they'll be at the next BotCon, though ive been wrong....
