help me decide

Looking to join the T6 family, but am not well versed in the value of vans and there seems to be so much variability. Any views on this van’s value would be greatly appreciate, are they asking a fair price? https://www.ebay.co.uk/itm/143613097006

T5.1 140 bhp or T6 150 bhp manual . Which is best ?. Will be using for everyday running round. And look to maybe put a rock and roll bed in at a later stage . Comments appreciated .
