Look at the Infiniti QX80. Now look at the Nissan Armada. See the difference? No? If it's hard to see, that's because they're essentially the same vehicle. But if you don't see the difference at a glance, you will in the price tag. The three-row 2019 Nissan Armada starts at just $46,790 while the Infiniti QX80 starts at $65,100.
