Chitty Chitty Bang Bang (1968) on Netflix

In England, circa 1910, eccentric Caractacus Potts works as an inventor, a job which barely supports himself, his even more eccentric father, and his two children, Jeremy and Jemima; but, they're all happy. When the children beg their father to buy for them their favorite plaything - a broken down jalopy of a car sitting at a local junkyard - Caractacus does whatever he can to make some money to buy it. One scheme to raise money involves the unexpected assistance of a pretty and wealthy young woman they have just met named Truly Scrumptious, the daughter of a candy factory owner, but Caractacus eventually comes into another one-time-only windfall of money, enough to buy the car. Applying his inventing skills, Caractacus transforms the piece of junk into a beautiful working machine, which they name Chitty Chitty Bang Bang from the noise its engine makes. At a seaside picnic with his children and Truly, Caractacus spins a fanciful tale of an eccentric inventor, his pretty girlfriend, his two children, and a magical car named Chitty, all involved in the faraway land of Vulgaria. The child-like ruler Baron Bomburst, ruler of Vulgaria, will do whatever he can to get his hands on their magical car; but, because of Baroness Bomburst's dislike of children, youngsters are outlawed, even the unsuspecting offspring of foreign inventors of magical cars.
