Buy Volvo D5

Tach, I looked around and my next vehicle will probably become a Volvo. I would like to have a V70 D5 with 185 hp and automatic. There is something to consider. A colleague said the car would be repair-prone, but I don’t know if he just wanted to make me unsure for fun, I didn’t find much here, so I assume that the cars are relatively robust. …and then I would be interested in the topic with the 2Takt engine oil as fuel addition. I didn’t find anything in this forum (maybe I’m too stupid as well). Does none of you put this in the car? … oh yes and still the request for a short info, to which friend I can turn in Cologne trustingly, if something is broken. Thank you…
