Convince Me!!!!!!!

so first of all praise to EUER forum quite nice here.I did not see such a close-up in any forum as here at smart-da the ghosts seem to divorce!! since the highly praised fault-free running power “knutschkugel” times the most fault-infested pushcart of the world!What I don’t like so much, however, is the personal hostility in some threads!!!is improveable! now to me: I drive a mercedes c220cdi from 2001 and I am extremely satisfied would never defy it. However, my friend wants to make the license soon and we do not see it to buy such a car yet something corsa,fiesta-like because the car should be more or less as an emergency solution for the one who needs a car (if one of us should already be on the road).Of course also as a “beginner car” for him.At the same time I am looking for “the”pass car for in between(my friend is certainly looking forward to driving the benz) I have smart since his appearance n hated how the pest-intermediately one could say I fell in love (have never sat in, let alone driven along!) only for me comes only the 2seater cdi in question. how can you convince me to buy him(advantage-disadvantages) many thanks for the answers in advance
