8. 1996 Volkswagen Drag Bus
Believe it or not, this is one of the most popular Hot Wheels castings ever. Although some collectors hated it when it was first released, it's gotten so popular over the last 18 years that companies like Penske and General Mills have teamed up with Mattel in the past to create Hot Wheels with their company names and logos plastered across the side. Coincidentally, the bus is also the heaviest Hot Wheels casting ever created. So, we don't expect it to go anywhere anytime soon.
