Volvo 850 2.5 / What do I have to pay attention to?

Salü Together. I’m actually at home at the Saabforum… But since I need a “favorable” winter car I hit a 850 2.5 GLE. He has 310000 down and has automatic! The rim was made last at 243000! Brakes at 284,000. He has a trailer. And he’s from MFK (tüf). He wants to look at it tomorrow. Test driving is not possible, the cooler and condenser is def. because a marten has found its end! (wild damage) Cooler I would have found on the demolition. that replace solte ncht the problem be! So and now my questions: When should the ruber be made again? What else would I have to pay attention to? It should not be a luxury car but it should be reliable! Thank you for your answers and greetings from Switzerland. Stefan
