From my guess, if Courtesy has been catering to the Z community for a long time on-line then they got into the .com business of selling parts early in the game. They were bound to make some mistakes. We as Xterra owners are just the lucky ones because they have worked out the kinks and have a WONDERFUL website coupled with great customer service.

I guess they learned from their mistakes from dealing with the Z folks and are now running things in a customer pleasing way. Maybe because the Z people had to start in the "wild west" of the .com parts business they still have the scars from all the growth and refinement of the system.

Just my .02
