I'm not a Star Trek fan but these castings are definitely really awesome! One of the very few Hot Wheels out there that actually come with a stand too. But these are popular castings for sure, they were pretty hard to come by! Anyways, these two castings are the U.S.S. Vengeance and the U.S.S. Enterprise NCC-1701 from the TV show Star Trek. The Vengeance is gray while the Enterprise is white. Also, the Enterprise I have is the battle damaged version, which is why some parts of it are on fire, pretty cool! Anyways, I'm definitely happy I was able to find these two pieces!
