What to pay attention to when buying a Twingo II?

Hello, I’m usually active in the Mercedes forum here. Now my girlfriend wants to buy a small car with a budget of 5,000,-€. As extras are only a split foldable rear seat as well as an air conditioning required. The color etc. does not matter. Since we first looked for a VW Fox and was advised from all sides of it, we noticed the Twingo as quite nice small car. Among other things we found the following at mobile.de: LINK What does it matter b to pay attention to the Twingo and there is already a Clio from BJ. 2006 with max. 80.000km for the budget? Thank you for your help!!
