The Packard was a make of car in the 1950s.
Dr. Emmett Brown owned a cream-colored 1948 Packard Custom Eight Victoria in 1955, which was used along with a flatbed trailer on November 5 to transport the DeLorean time machine — concealed beneath a tarpaulin — to his lab, and to Courthouse Square on the night of November 12 for Doc's 'weather experiment'.
Doc let Marty McFly borrow the Packard for the Enchantment Under the Sea dance at Hill Valley High School on November 12. The car became the scene of the scuffle between Biff Tannen, Lorraine Baines, and George McFly.
After Doc restored the DeLorean to perfect working order, including installation of vacuum-tubed time circuits and new whitewall tires, the Packard and flatbed trailer were used once again to haul the DeLorean to the Pohatchee Drive-In Theater in preparation for Marty's trip to 1885 to rescue Doc's older 1985 counterpart.
The Packard's license plate number was 8N39742.
