Car

A car is a Muggle wheeled vehicle propelled by a motor used to transport one or more people. It is a very popular mode of transportation for Muggles, and it is known to have been used by wizards on some occasions. In the Muggle world, usage of cars is regulated by devices such as traffic lights and parking metres.

Some Muggles viewed cars as status symbols and Vernon Dursley in particular tended to judge people by what type of car they drove. Harry Potter, however, felt that Vernon wouldn't have taken to Arthur Weasley even if he drove a Ferrari (a brand of car known for top-of-the line luxury.) Harry Potter was told by his uncle Vernon and aunt Petunia that his parents, James Potter and Lily Evans had died in car crash. This, however, was a lie to conceal from Harry that his parents were wizards, and they had died from Killing Curses cast by feared Dark wizard Lord Voldemort while trying to protect him.

Wizard use of cars
Despite generally showing disinterest or even disdain towards Muggle artefacts, many wizards are known to be envious of Muggles for their cars. The British Ministry of Magic maintained a fleet of staff cars that could be borrowed by employees, and even staunchly anti-Muggle pure-bloods have been known to purchase luxury cars such as Rolls Royces.

Although a car is defined as a Muggle artefact, and is therefore illegal to enchant under British wizarding law, nevertheless there are a few enchanted cars in Britain. The Ministry of Magic has cars that navigate traffic with magical ease. Mundungus Fletcher "borrowed" a car to take the Weasleys to visit Arthur in the hospital on Christmas day; he had magically enlarged it to fit more passengers. Ron Weasley, Alfie Campbell, Harry Potter and Cho Chang were known to own one of these in their adult years.
