The rarest vehicle on Earth is often considered to be the 1955 Ferrari 410 Sport Spider, of which only a few were made. Another contender is the 1937 Talbot-Lago T150-C-SS Teardrop Coupe, with only about 14 units produced, making it extremely sought after by collectors. Additionally, unique one-off vehicles, such as custom-built prototypes or concept cars, can also be classified as the rarest due to their singular existence. Ultimately, rarity can be subjective depending on the criteria used, such as production numbers, historical significance, or existing examples.
