Buy 850 or V70, risk?

Good evening, I plan to buy a car (Kombi) for the truck. Up until now I was so fixated on the Mercedes W124 T. The truck had been sold to the truck before, but I had lost a bit. But now I have looked at the market again, and tend to go back to the Volvo… What for the W124 says: I know someone who knows the W124 very well, screws, people know… At the Volvo I would be alone. But the Volvo has no rust problem, and the equipment seems to me in what is so on the market, mostly better, v.a. Airbags. How is your experience: can you buy a 850 / V70 alone as a loader without falling ill into the trap? I can also hear a 3 gulf for a friend who had no idea, I have to say another loader, I have to test something else. I have no accident damage (Spold measurements, Knitter in the engine room) and one with oil in the cooling water.
