Kia has been making its own cars since 1974. Prior to that, all of Kia's passenger car and motorcycle production was licensed from Mazda and Honda. Some of Kias first models were jointly developed between itself, Mazda, and Ford. But, it took a while later before it made its own vehicles available in the US market. Specifically, in 1994, when its Kia Sephia was sold on American soil. This was then followed up by the popular Kia Sportage. Near the tail-end of the 1990s, Kia then unveiled the Optima and Sedona in the US, as well. Finally, in 2006, Kia broke ground on its first US-borne production facility.
