Hello! I have to get a Smart Cdi because of the fuel costs. I actually only know two driving areas: Either the pure city of Berlin in ultra-short-distance traffic or highway/road stages of 300-1000 km at a time. How does that make the Smart? It doesn’t matter to me speed but the comfort. So how are the seats of the Smart and the driving characteristics on the train? Because the Twingo with which I am currently on the road becomes quite restless on the highway and z appelig, my former Audi A4 was at 120-150 absolutely quiet one has arrived completely relaxed. How much diesel does the Smart Cdi approve at about 120-140? Because 3.5l consumption would be a dream… Thank you for the answers!!! Matthias
