The Knight Bus

A magical bus that appeared whenever a witch or wizard was in urgent need of transportation, all they had to do was stick a wand arm out at the kerb for it to instantly appear. Distinctive in appearance, the Knight Bus was purple and triple-decker with seats during the day and beds at night. Harry Potter accidentally summoned the Knight Bus when he was forced to escape Privet Drive, where he endured a bumpy ride to the Leaky Cauldron. During Harry's encounter with the bus, Stan Shunpike was the bus conductor.

A single fare for the Knight Bus came to 11 Sickles, although hot chocolate and a tooth brush would cost you extra.
