While looking for some Nissan Leaf brochures ( search triggered by http://www.imcdb.org/vehicle.php?id=1030571 ) i found this website : http://www.auto-brochures.com/index.html . Similar to http://oldcarbrochures.org/ but also including foreign manufacturers , mostly for US market

autopaper.com can be interesting too. Its main purpose is to sell brochures, so most of the documents are not fully displayed, but there are scanned pictures that may help identify the vehicles.
