Factual error: When in Amsterdam, there are a number of mistakes with Hanna's car. First off, it's a brand new model, but it has a numberplate from a series six years ago. Second, that numberplate is a flat sticker, while Dutch numberplates are made with very thick plastic letters. Third, the registration is 87-UYM-3, which wouldn't be used, given that Dutch numberplates don't use vowels.
