One of the Gräf &amp; Stift luxury limousines, a "Double Phaeton" (engine no. 287), was bought by on 15 December 1910. Harrach's car was fitted with a four-cylinder engine delivering 32 PS. In 1914 in Sarajevo, the Archduke Franz Ferdinand of Austria and his wife rode together with Harrach in this car, when Gavrilo Princip assassinated the Archduke. The assassination provoked a series of diplomatic manoeuvres that quickly led to declarations of war and the onset of the First World War. Ironically, the license plate of this car reads "A III 118", which can be read as "Armistice, 11/11/1918" - the date the hostilities between Germany and the Entente allies ceased.
