plump for the Ford or the Renault
Citroen you mean...
Berlingo owner here. I love it.
I have taken the double seat out of the back, left the singly which also folds up and so it makes a great little bike van.
You may of course be talking about the purely van one.
I think the car-based one is more versatile though.
I got three of us into mine with 3 bikes and all our camping gear for 3 weeks in Europe last summer. Worked well but it was a squeeze. I built a false floor in mine so I could shove a few bits underneath.
Normally though, I can get probably 3 bikes in without taking the wheels off, but it's more comfortable with the front wheels taken off.
