Purchase advice

Hello everyone with this Clio:http://suche.mobile.de/…/208712780.html?original=PARK# Will the days also try. Do I bother from the first view only the yellow badge, can one retrofit the one on Euro 4, which he easily gets the yellow badge? I don’t know myself with Renault at all, am rather VW driver, but with the prices, which are demanded even for a 2006 Golf Diesel, I think about that still 3x. Interesting for me feedbacks about r possible weaknesses, on which I have to pay attention during a test drive etc. For soon answers from you experts, if possible also from people who drive this model, I would be extremely grateful. In this sense
