H1, T5, Vito / Viano or anything else???

Hello dear community, I have a concern and I am already a burnt child (T5 engine damage). A bus is wanted. Budget 8.000€. Automatic and climate must be. Lots of space, i.e. 6 seats minimum and comfortable stroller with pure without having to operate origamie art. Isofix would also be good (if necessary retrofitter). Diesel or LPG. Driving power approx. 25,000 to 30,000 km pa. With this budget not all too much is in question: Vito, T5, H1 would now be from my point of view Kandi The Vitos are unfortunately eaten up by the rust, with the T5s the engines burst and I don’t know anything about the H1. The bus has to transport regularly at least 5 -7 people and from time to time even loads when the back bench goes out quickly. Ideas and recommendations with the budget? Thank you in advance.
