'Grease' - 1948 Ford Deluxe
The 1971 stage musical "Grease" got a big-screen adaptation in 1978, starring John Travolta, Olivia Newton-John and the late Jeff Conaway as Kenickie. The story of lovers at a 1950s high school was a monster hit, thanks in part to songs like "Summer Nights" and "Greased Lightnin'."
The "Greased Lightnin'" sequence featured Travolta and Conaway dancing on a dilapidated 1948 Ford Deluxe that turns into an "automatic, systematic, hydromatic" dream machine by the song's end. According to Karl Brauer of TotalCarScore.com, this car ranges in price from $10,000 to $50,000, depending on its condition.
