As far as I am aware the vans had cords until the end of production. Only the Cooper models had the metal handles fitted as standard.
I think for ease of use the cord is better as you do not have to reach behind to get to the handle, but I have found that when you take a passenger who is unfamilar withthe cord the use it to close the door, or try too, and it bounces back open.
There are quite easy to change, all you have to do is remove the inner latch mechanism and swap the parts over.
There were various accessory handles made aswell, the most popular being the bent tubular ones with the wooden knob on the end.
