Purchase of second-hand vehicles

Hello! I plan to buy a Grand Scenic 3 Ezl. 2016 1.5 dci 81 kW. I drove the predecessor Bj 2008 with 76 kW (normal Scenic) Unfortunately I had an accident (total damage) I had no problems on more than 200,000 km except small things(AGR valve, supporting joints) Is the 3 Scenic also so reliable or rather a problem child? I am looking for exactly the 3 he Scenic because I am disappointed with the 4 for the purpose of offering space…
