Hello I'm going to buy R50 Pathfinder, probably 2001-2004 year. When searching through cars.com or autotrader.com I found that there are SE,LE trims of the pathfinder. I want 4x4 version and as I found out on SEs knob is mounted on the flour and on LEs it's mounted on the console. Is there any difference? I'm also interested what capabilities does R50 have? I know it has 2wd, 4h, 4l modes. Does it have Center Differential Lock and how it's activated? Thank you
