Purchase advice Mazda 6 2.0l Automatic

Hello to the round, looking for a suitable station wagon we came across this offer:https://suchen.mobile.de/…/details.html?… I have read here in the forum that the 165ps petrol engine is almost unproblematic. Are there things I have to pay particular attention to during a possible test drive? Is the price correct? What can you possibly get out of it without being rude? Would I be more than happy about some tips and ideas from you. LG
