The car pictured on the front cover of the UK edition of the "Harry Potter and the Chamber of Secrets" is a Turquoise Ford Anglia 105E with the registration number HOW777.

J.K.Rowling arrived in a vehicle very similar to that shown on the cover when she launched the next Harry Potter novel : "Harry Potter and the Goblet of Fire.
The Turquoise For Anglia was bought by Arthur Weasley for the purpose of taking it apart in his shed to see how it worked. In the process of taking it apart and reassembling it, Arthur bewitched it to be able to fly, installed an invisibility generator and also instilled it with a mind of its own. He also magically expanded the passenger and storage space so that an enormous amount of luggage could fit in the boot, and an amazing amount of people could sit comfortably inside. Fred and George flew the car a number of times, once all the way to Surrey to rescue Harry from the Dursleys. Shortly afterwards Harry and Ron made a dramatic flight to Hogwarts in Scotland, crash landing into the Whomping Willow. The car is severely damaged by the tree (that beats up anything that gets too close to it). The car ejected Harry, Ron and their luggage and fled into the forbidden forest. It is still there, trundling about the forest like a wild animal.
