The flying car

A dedicated fan of Muggle memorabilia, Arthur Weasley often enjoyed tinkering with non-magical items and adding a few of his own enchantments. One such item was a rusty, blue Ford Anglia which, thanks to Arthur's enhancements, was able to fly, had an invisibility booster and could fit the whole Weasley family into the back seat.

Although the car was strictly illegal, this didn't stop Ron and Harry borrowing it to fly up to Hogwarts when they found themselves blocked from the Hogwarts Express. Unfortunately their trip ended in disaster when they crashed into the Whomping Willow - and the car escaped.
