My rural postal carrier uses a Cube, & it has been a great vehicle for her. I believe her daily route is over 100 miles. On nasty winter days, she will use her old Dodge Durango. Several rural carries in our area are now driving Jeep Wranglers set up for right side driving (special order vehicles). She somehow sits in the middle of her Cube and makes it work.
My previous postal carrier alway drove a Reliant K car. He used those cars for years. If your car isn't set up for right side driving, a bench seat was popular.
I don't mean to totally bash Nissan, but their reputation is tarnished. If I ever bought a used Nissan, the Frontier would be my only consideration, too.
