Euro – Van: which one is best? At all good?

Hello! As a car-interested person I am always asked in relation and acquaintance, when it is about new cars. Much is of course only “only for interest”, therefore I ask for indulgence, if this purchase advice does not follow any actual purchase. Currently a family with 2 small children is looking for a new / used car with ideally 2 sliding doors. The high roof combis are all already through, these would be ok, but not great. Because they bribe by favorable price, In addition, a trailer load of at least 1.5 tons would be good, but not very important. In case of doubt, there is a 20 year old combination with over 2t ready. This trailer load also offers only the fewest HDKs. The possibilities in this field are quite thin sown, therefore to the actual question: What is to be kept of the so-called Eurovans Fiat Ulysse, Citroe C8, Peugeot 807 and Lancia Phedra? Which engine/gear combination is to be recommended missing, which brands are better than others, are there fault guarantors e.g. with electric sliding doors or sliding roofs? Or is this series generally not recommended? Sometimes completely detached from driving profile and budget. Thank you!
