As the name suggests, the Toyota Collection is not a factory museum, but has been based on a private collection.
Following the passing away of the collector, Toyota Germany acquired the cars and ad hoc public openings are scheduled to the first Saturdays of each month, dedicated to a particular theme, usually a model or a model-series.
The Toyota site in Cologne hosts the headquarters of Toyota Germany and also the technical centre of Toyota’s sports department (Toyota Motorsport). The latter is however not accessible to the public at all, unlike the collection. However, on seldom occasions, a few selected (and fast 😊 ) applicants get a tour at the Gazoo Museum as well.
