Why did Nissan use a leaf spring rear suspension instead of coils or something similar? Was this to increase ground clearance???

Because it was cheap.

A rear coil suspension would have had more travel but would have been more expensive.

When you talk 500-1000 per vehicle it starts adding up real quick. Heck when I was at GM if they could cut 50 cents out of a vehicle they were estatic!

To be honest, coil vs leaf really isn't a cost per vehicle thing, it's a cost of design thing. The parts to do a coil suspension cost about the same (maybe even less) than a leaf sprung system. They already had the leaf system desinged from the Frontier, so they used it on the X and just moved the axle over.

Yep!

While an ancient design, the leaf spring system in the rear of a vehicle is really quite good. I've seen some amazing articulation in the rear with the help of good spring packs.

On a rear application, a good leaf spring system isn't giving up all that much to the coils.
