premise: The Volkswagen Polo Mk3 is the third generation of the Volkswagen Polo supermini car and was produced from 1994 until late 1999 and some models in 2000. It was available in hatchback, sedan and wagon body styles. It shared the same platform and initially a similar design as the contemporaneous Seat Ibiza (hatchback) and Seat Córdoba (sedan and wagon) models.
hypothesis: The contemporaneous Seat Ibiza (hatchback) and Seat Córdoba (sedan and wagon) models were  produced from 1994 until late 1999 and some models in 2000.
reason: The context only specifies that the Seat cars shared the same platform and design but not necessarily the same exact production years. Therefore, my statement is neither correct nor definitely incorrect.
