What me intriguied most at the Renault Estafette was the sliding door on the driver's side. As a young child I remember the postal office used these vans as did several other companies delivering goods at my parent's store. The sliding door was a very practical solution, because the driver could get in and out the van without having to open the door everytime.
The engine of the Estafette was dramatically underpowered, so it was mostly used for quick deliveries rather for movements of large and heavy loads.
