Car up to approx. 3000€

Hey, I’d like to get opinions from more experienced people than I am myself or my environment. My last car was a Corsa D 3 door with 69hp. But since this one has become too small and was too undermotorized, it’s supposed to be something bigger with more power. And all for about 3000€ (+ – 200€) I’ve already looked around the stock exchanges and parked the following models. Ford Mondeo Limousinehttps://suche.mobile.de/auto-inserat/ford-mondeo-ghia-navi-xenon-tempomat-pdc -recklinghausen/287007584.html?action=parkItem Audi A4 Limousinehttps://suchen.mobile.de/auto-inserat/audi-a4-lim-2-0-euskirchen/279614115.html?action=parkItem Ford Focus C-Maxhttps://suchen.mobile.de/auto-inserat/ford-focus-c-max-1-8-fun-x-t%C3%BCv-au-neu-klima-dortmund/2875765111.html?action=parkItem Ford Focus Tournamenthttps://suchen.mobile.de/auto-inserat/ford-focus-tournament-1-6-t%C3%BCv-neu-winterreifen-m%C3%BCnster/288915240.html?action=parkItem What do you think of this? Timeless design as well as interior equipment.. Good would also be the possibility to exchange the old original radio for a double Din. And I still have an important question: Up to what mileage would you still buy a car? I have tried to see that it is less than 150 000 km, everything about it is already a bit painful for me :/. I am curious about your answers. MfG Dot.
