V70 Diesel – buy with a lot of mileage?

Hi, I’ve been reading here for a while, but I’m not sure about buying a V70. What I’m writing are all impressions, I don’t have a real idea of cars. I pay attention to seriousness when choosing the dealers – I can estimate that to some extent. The price frame allows me – either a passat TDI ~2 years old with ~50 TKM (there are several offers – probably leasing resetters) – V70 Diesel 163 HP ~3 years with ~150 TKM The Volvos saw with many KM ste ts good off, but 150 are already much more than 50 and a 2 year old passat also has no obvious quirks. Can you recommend a vehicle that already has ~150 TKM down, but all that just ran on the autbahn? Which wear symptoms come to me in the next few years? On the other hand: Is a passat with 50 TKM the better choice in the medium term, because the quality of Volo makes a subjectively good impression? Many greetings, rawaho
