The longest car ever made was over 100 feet long - Apparently.
The Mercedes-Benz 450 SEL 6.9, built in 1979, was a custom-made, one-off vehicle commissioned by a German aristocrat. Measuring 102 feet 1.5 inches (31.1 meters) in length, it was certified by the Guinness World Records as the longest car in the world. The massive vehicle had a 7.3-liter V8 engine, produced 300 horsepower, and was reportedly used for promotional events and exhibitions before being retired to a museum.
