There's a car that's been running non-stop since 1966 - Apparently.
The Cadillac of the future, a 1966 Cadillac, has been driving continuously for over 55 years. It was started on February 28, 1966, at the Daytona International Speedway and has been driven over 3.8 million miles. The car has been kept running by a series of drivers who have taken turns behind the wheel, with the current driver, Bob Wian, taking over in 2000.
