Secondhand purchase Omega 2.5DTI

Hello everybody, I’m looking for a replacement for my little one right now. Combi and Diesel. The Omega 2.5DTI Caravan is an interesting choice. I don’t want to know anything about acceleration and consumption, you can read it elsewhere. But what I want to know is whether there are typical quirks or something special that you should pay attention to when buying? Thank you very much.
