Knowledge 1: List of best-selling automobiles
While references to verify the manufacturers' claims have been included, there is always the possibility of inaccuracy or hyperbole. Also note that a single vehicle can be sold concurrently under several nameplates in different markets, as with for example the Nissan Sunny; in such circumstances manufacturers often provide only cumulative units sold figures for all models. As a result, there is no definitive standard for measuring units sold; Volkswagen has claimed its Beetle as the bestselling car in history as it did not substantially change throughout its production run. By contrast, Toyota has applied the Corolla nameplate to 11 generations since 1966, which have sold over 40 million through July 2013. [SEP] Knowledge 2: 1973 oil crisis
Some buyers lamented the small size of the first Japanese compacts, and both Toyota and Nissan (then known as Datsun) introduced larger cars such as the Toyota Corona Mark II, the Toyota Cressida, the Mazda 616 and Datsun 810, which added passenger space and amenities such as air conditioning, power steering, AM-FM radios, and even power windows and central locking without increasing the price of the vehicle. A decade after the 1973 oil crisis, Honda, Toyota and Nissan, affected by the 1981 voluntary export restraints, opened US assembly plants and established their luxury divisions (Acura, Lexus and Infiniti, respectively) to distinguish themselves from their mass-market brands.
