Family car for four people up to 10,000 euros

Hello forum, I have to prepare for a farewell to my Vectra (272,000 km, MY 2004,5). According to the workshop, the “three flaps” (or so similar) are added to the exhaust manifold with soot and diesel. Therefore, a diesel/gas mixture penetrates into the interior of the vehicle in the stand. Of course, you do not get the part individually and the whole manifold would have to be replaced. It takes 1.5 days in the workshop and costs a total of approx. 1000 euros. At -10°C outside temperature it won’t be really warm in the car anymore. ?? Well the big question: What now? I had already shot myself into the Jeep Patriot, but I guess now in the pondering, because it is no longer sold in Germany and spare parts are probably quite expensive. Brand-technically I am almost painless (apart from Lada, Dacia, etc.), only a Opel it doesn’t have to be again. I would like to have something in the direction of SUV. ch ok. I drive about 20,000 km a year. Most of it over land. What would your suggestions be? An old Volvo, an old Benz or Audi or rather a newer car and not a premium brand? I am grateful for suggestions.
