I am starting to believe the MO is really the bastard child of a 70's AMC product. It's just possible one of Nissan's current senior design engineers may have cut his teeth on the Gremlim program back in the 70's.
Back then the Japanese car companies clandestinely sent a few of their young engineers over to the States to learn from their Detroit counterparts. I think some young buckaroo was sent to AMC as a punishment and now he is working on the MO design team! I guess it could be worse, he could have been assigned to the AMC Matador design team!
