can anyone tell me if the rear seats are removable and also can be folded flat on the fiat doblo 1.4 8 v active so you can use it as a van . Also are these reliable work horses as I am thinking of changing my citreon berlingo mulispace for a fiat doblo active 2009 . Does the fiat doblo active have a slightly bigger carrying capacity as I would be using it for carrying boxes .Are there any problems to look out for when buying
