...So I was driving north on i75 near Mason, OH when this camouflaged SUV catches my eye. I proceed to snap some pictures with my (ancient) blackberry phone when the driver gets on the radio to let the chase car know and they slow down to about 35mph in the middle lane of i75. I know how slow because I got in the right hand lane ahead of them and slowed down too. After snapping a couple more side mirror shots I decided I'd better speed up.

Exhaust tips look identical to the "spied" RX from a couple months ago. Mirrors look like a similar assembly design to the NX.

 

Nice catch but there's a discussion about the 2016 RX here.
