Volvo V70-1/850 Purchase advice

Hello dear MotorTalkCommunity! Thank you for getting into the forum. I’m standing in front of my first used car purchase, actually even the first visit ever? I’m looking for a car for a longer trip next year and I’m now convinced it’s supposed to be a Volvo 850 or V70-1. The price range is very wide, partly the massive price differences are also obvious to me, partly but also not. I assume that I have to invest a lot more before the trip anyway and therefore think about taking a cheaper, more worn vehicle as a base. Now I have found this offer in the neighborhood and arranged a visit:https://ssearch.mobile.de/vehicles/details.html?id=334535432 Do you think that the car is worth its price? I have the hope to push the price still a good bit. Do you have here tips for me how I can do so well? Do you have an approximate idea of which additional expenses I would have to start from? Since I’m unsure, I thought that after the visit I’d like to ask you a less in case that I’m not going to talk about a bit more about it.
