Which one is better? Premium combi

Moin to the country, in the course of the separation my wife takes off. She will take the Volvo with her. As the children stay with me, a station wagon has to enter the house again. The separation will leave financial traces, therefore the “new” car must not cost a lot of money in the purchase and it should be very reliable. After some considerations I have now come to the following cars: BMW 5er Kombi Audi A6 Kombi VW Passat Kombi The above mentioned cars are in my opinion qualit With my financial possibilities, one of these vehicles will probably be at least 10 years old and probably already have around 200,000 KM on the hump. I hope that the cars are so good that they are still really good and not prone to repair even at this age and with this mileage. At the Audi I am very impressed with the fully galvanized body, at the BMW I like that it has no timing belt, at the VW the size. Since I am vie I do not include these cars, at least until I hear something else. Of course, a Volvo would also be in question again, I also like Saab, but I don’t know exactly why. I would like to have one of these cars with autogas, diesel could be an alternative. I would be very grateful if you would tell me what I have to pay attention to on which models, or when I should definitely leave my fingers off. Thank you.
