Toyota ProAce City Verso – Timing belts in oil?

Hello together, We have the possibility to buy a Toyota ProAce City Verso cheaply (for the price the dealer would offer). The car would be perfect by the way and at Toyota I have no concerns either. However, I now have to read that it is practically a car of the PSA Group, which also makes itself noticeable to a reduced warranty extension to 5 years. Now I have come across in a forum post that the 110 hp engine has run the timing belt in the oil In fact, I thought that only the Ford Ecoboost had. Since I have this currently and sometimes the well-known problem this would be a KO-criterium for me. Is this also the case with the engine with 96kw / 131 hp? Would I be very pleased about experiences.
