From all of the bitching in the driveway, vans were not pleasant to work on the engine. Some of them had to remove a cover from inside the van to gain access, and that cover tended to not be well insulated and was the source of a lot of heat. Not much of a firewall as a car with the engine fully separated from the passenger compartment.
There were a lot of things people did not like about vans available in the land of Yanks. The Limey vans are not the same, so do not equate your experience as being the same.
