I’m someone who’s owned a string of second hand vans, and would now only ever buy new: it’s incredibly hard to find non-abused vans. Very different from 2nd hand car market.
Although Pip may have a good contact.
The other exercise I’ve done with some of my work is modelling it low carbon, which mainly involves not having a van at all.
The solution that emerges from that is a bicycle with a trailer. So: a Makerspace communal trailer anyone?
