Hey LVP. No big difference between the two. I have a 2004 4.4i that i'm in the process of selling right now. I think the only difference is that the 2006 came standard with Bluetooth.

If youre interested in coming down to the US, you can always buy mine. There are plenty of people on the forum who would vouge for it being near perfect..

oh and all 4.4i have rear self leveling suspension. no need for four corner adjustable air suspension for towing
