Tell me more about the 360 Package...

[BMWBig6]

Just brought home a clean 1-owner 2010 Nissan Rogue with the 360 package yesterday (still under the original factory warranty for 7 more months). I really wanted a reverse camera, but the 2011 models were out of my price range so I'm pleased that I was able to score a cheaper 2010 with the 360 package's camera.

Is the 360 package a relatively rare option? I didn't find very many during the past few weeks of searching. Or are they pretty common but not usually listed as such or indicated in most classified descriptions? (I'm already trained to look for the 360 rear badge, chrome on the grill and large rear spoiler as tell-tales even if "360" is not listed.)

Also, how was I able to find a 2010 Rogue 360 with leather? According to the model year specification guides posted above, the 360 was only available on the S trim, and leather appears to only have been available on the SL trim. So how could one find both features on the same vehicle? Did the 360 come with leather too (even though it's not listed as part of the 360 Value Package in Nissan's sales literature)? Or is the order guide incorrect, and leather was always available as an a la carte option, regardless of trim in 2010?
