Comet was a British automotive brand established in 1921 by the Preston Autocar Co. Ltd. The company focused on producing light sporting cars, which were characterized by their simplicity and performance-oriented design.

The Comet model featured a 10 horsepower, four-cylinder engine, paired with a four-speed gearbox and shaft drive. Its design was minimalistic, showcasing a two-seater body that lacked doors and a bonnet, emphasizing its sporty nature.

While the exact location of the factory remains unknown, it is believed that the operations were not based in the West Central district of London, suggesting that the area may have served primarily as an office for the company. The brand's production was short-lived, and it did not achieve significant recognition in the automotive market.
