Car up to 5000 € (Polo/similar) for small drivers (approx. 5000 km per year)

Hello. We are looking for a car for my father (73) up to 5000 €. A VW Polo would like him best. However, we wanted to see outside the box anyway. Although I can say: With Asian car brands it becomes difficult (apart from Kia, because he knows a Kia dealer and has good contact with this one).Requirements: The demands are not all too high. He would regularly drive short (5 to 15 km) routes (winter + summer, approx. 5000 km per year, almost only country road/localities) u A polo fits perfectly from the size of the trunk and interior. It also likes it visually. TFL and preferably a 5-door (because of the smaller doors) would be desirable, but not a must. Year of construction should be newer than 01/2008. 60 to 80 hp and (maximum) 50 000 km on the tacho would be great. Remember that the vehicle would only get a (!) covered parking space. Since I bought a car only once in my life h However, I have a technical understanding.Autoscout24 and mobile.de: With the above requirements it becomes difficult for the polo. Most of the year 2007 and older or about 100 000+ km on the speedometer. Alternatively, Opel Corsa, Peugeot 207, Kia Rio, VW Fox (and Mitsubishi Colt?) would be in the budget and feasible. In my search I also found two bargains (Mazda 2 (2009) and Kia Ceed (2008). I noticed a relatively large number of Fiat Grande Punto. There are practically very good prices. Where is the catch?My concern: The vehicle must certainly last five to eight years and buy a nine-year-old polo now. Especially when it comes to typical defects or the question ‘what do I have to pay attention to when buying’? At the Peugeot 207 the rear axle seems to be very vulnerable – the other brands I absolutely can’t What do you think / think? Should I pay attention to another brand or even check out one of the above? Thanks for further help!
