Meaningful First Car

Servus, in search of a suitable first car I discovered the A5 sportback with the smallest engine for me. However, since this one has already a few kilometers on the hump in my price window (max. 12,500 better 10,000) I wanted to ask if such a car as a first car makes sense at all, and there are perhaps better and still nice alternatives. The car should be as comfortable, safe and resilient as I will drive often and far. -Operation(approx. 25km) – Berufsschule (400km Blocklehr) -Baustellen in all DE (approx. once every two weeks) The car should be a bit more expensive, because I want to snap on with a study after my training so that my financial possibilities for large repairs or even a new car are very limited. Thanks already for your answers
