The first of these, built almost completely by Royce himself, was a success in almost every way: it started easily, ran smoothly and was very reliable. It never failed to impress everyone who saw it rode in the car, including Rolls. While he was a university student at Cambridge, Rolls acquired a French Peugeot.
