Questions about Fox 1.2, 54hp…

Hello, the Fox 1.2 is a three-cylinder… is it as long-lasting as a four-cylinder? Does the steering chain? How often does the Fox have to be for maintenance and how expensive is it? How high is the speed at 100km/h and 120km/h? And what is the realistic consumption then, at the speeds in long-distance operation (about 50km at a time).? Since I am looking for a cheap small car, which should run and keep many kilometers, the Fox has come into the race. Unfortunately I do not know any Fox – owner, which one could ask personally.
