Volkswagen
From Tardis Wiki, the free Doctor Who reference
Volkswagen were car manufacturers on Earth, at least during the 20th century. Mickey Smith and Sarah Jane Smith had yellow Beetles, a type of iconic Volkswagen. Markings on these Beetles clearly showed that the manufacturer was also known as VW. When he left for Oxford, Luke Smith took possession of his mother's old VW. (DW: Rose, SJA: The Nightmare Man)
