Driver looking for the perfect car up to 600€

Hello, I have already searched here and asked, but my view has changed a bit, here a new thread: I am looking for a car for 5000 Euro or for a really good car also 600€. My dream car is actually a Mazda MX 5, unfortunately only 2 seats. For the budget is often recommended Toyota Yaris / Corolla, Ford Fiesta etc. Basically I am brand open, but unfortunately I don’t like the old Ford models too much optically. My requirements: -Mind. 4 seats -enug Performance to see not only rear lights on the BAB -right problem-free -most favorite limousine -favorable maintenance -optically it should make it a little bit. I looked at a few Volvo S40, are optically good for me, how is that? Otherwise I would like a Mazda 3 but also Mazda 6, both however rust problems. Toyota Corolla would then be my absolute emergency solution, good car, little problems, not too expensive. What can you recommend? Thanks
