I used a Nissan NV200 for a while and found it comfortable and easy to drive, it was the first vehicle I'd driven that was fitted with a parking camera. Not sure about long term reliability or running costs though.
Check out insurance costs before you commit to anything, they can be much higher than you expect. My son had a Ford Tourneo Connect (the seats and windows version of the connect, so a car not a van) then changed to a Transit custom van to transport his instruments, the insurance was well over double.
