Rallying
Rally is a form of motorsport that takes place on public or private roads with modified production or specially built road-legal cars. It is distinguished by running not on a circuit, but instead in a point-to-point format in which participants and their co-drivers drive between set control points (special stages), leaving at regular intervals from one or more start points. Rallies may be won by pure speed within the stages or alternatively by driving to a predetermined ideal journey time within the stages.
Banger rally
A banger rally is a rally in a scrap or low value car on public roads. The event is a non-racing variant of banger racing. A banger rally may also be a charity rally where the teams taking part in the event also raise money for charity. 
Banger rallies chiefly appear to be a United Kingdom-based phenomenon and most involve driving through Europe to various destinations where the cars are environmentally scrapped, sold or auctioned for charity. Some events have a limit on how much a participant can spend on buying a car or the size of the engine. Participants in the events often decorate their vehicles with the stickers of sponsors or customising to a theme from popular culture.
