8. 1945 North American Aviation P-51D Mustang ($2,250,000)

Arguably America’s most capable fighter jet during the 1940s was the 1945 North American Aviation P-51D Mustang. This aircraft was incredibly important during World War II as it was proven that the ground fight could not be won without the assistance of fighter jets. 

The 1945 North American Aviation P-51D Mustang was an invaluable tool in helping allied forces win the war. These fighter jets enabled bombing to resume after heavy losses were suffered in 1943. 

Interestingly the P-51D were developed to be exported to Britain, who then modified the jets to include uber-powerful Rolls-Royce Merlin Engines. It was because of these engines that the P-51D Mustangs became so capable. 

Each of these planes was equipped with six 50 caliber machine guns, and they were able to carry 2,000 pounds of bombs or ten 5 inch rockets. Only 8,000 North American Aviation P-51D’s were ever produced, which is why when one becomes available, it costs an exorbitant amount to purchase.
