I have driven loads of vans in my time, I'm currently in a connect and there shoite, Doesn't help it's limited and tracked though!
The citroen/puegeot is ok had one for 3 months at one company and 2 head gaskets later and other annoying problems I went. Don't know how long it lasted after me! I was the 3rd driver of the van so it had been abused already.
nissan serena / Ldv cub. I cried when i got given one of these, Nuff said
My favourite was a Renault Kangoo, Often overlooked but for a van I abused for over 4 years solid at about 40K a year I had no issues or problems, until I blew it up in oxford with over 175K on the clock.
