There is a longer scene in the movie showing a bus trying to turn around on muddy soil. The bus is a Rocar bus, which has been produced only after 1990, and it has stickers on its doors, which surely have not been used before 1989.

The end scenes shows Eva on board a ship, the "Prinsendam" of the HAL (Holland America Line). However, historically the HAL has had two ships of that name, the first one tragically sank of the coast of Alaska in 1980, thankfully without casualties. The second ship of that name only joint HAL in 2002, before that it was know as the "Royal Viking Sun" since it's birth in 1988. In the period Eva supposedly received the letter from her younger brother there was no ship with that name.
