I've gone from Mondeo to Transit. Vans are just better in every way.
I would buy an old people mover, pull the rear seats out and tint the windows. That way you don't have insurance issues or pay extra tolls.
The one between the Mondeo and Transit was an MPV. Modified ones are a PITA to insure, the van was a doddle, and a lot (like nearly half) cheaper. Van for private use doesn't pay extra tolls, although the definition is whether it has a window in the side. Ferries cost more though
So removing rear seats that often are designed to be removed or folded away is a modification but putting a side window in to avoid higher tolls isn't a mod? Things have changed a bit because private insurance on vans used to be tricky.
Yes you can be lucky and find a well cared for van that was run by the owner rather than an employee who doesn't pay for tyres, fuel or breakdowns and hates the van.
Buy well and I'm sure it will be bullet proof not having to carry heavy loads or constant stop start round a major city.
