Nash Metropolitan at Raleigh
On December 7 - 8, 1953, The Nash Motor Company tested their new economy car, which would become the Metropolitan, at Raleigh Speedway. Two cars, serial numbers 1009 and 1013, were tested for speed endurance and fuel economy respectively. The tests were run and certified by NASCAR as an independent party to gather data to be used in sales literature.
