Recommended purchase V70 / V60

Moin together, I would like to buy a combination. Either a V70 or a V60. Preferably it should become a diesel. I have been looking for a bit longer and have found the 4 cylinders as well as 5 cylinders. I myself have a 850 5-cylinder and would like to take one again. What about the durability of 4 cylinders diesel with 181 hp? I found a V70 D4 which is interesting. What are the typical diseases? Is there something to consider? What are your experiences? Thank you and say hello to Nilsco
