Steady on. One of my favourite cars was an old Fiat Uno that my wife and I dove all around Europe, INCLUDING on the German Autobahn. The old 700cc engine did a great job, as long as we stayed in the right hand lane.
On the one occasion that I did get stuck behind a truck and tried to overtake it, it was clear for at least a kilometre behind me, and in the two seconds it took to pull out into the next lane, there was a BMW on my tail, standing on its brakes, horn going furiously :p
Certainly got us places in city centres and villages that the Disco couldn't go.
