Buying an LR3 and have ?'s!!!

[TheTank3]

So I'm looking to get an LR3 here in a month or so and I'm moving from a 2007 Nissan Armada. I loved that SUV aka The Tank. I'm looking to get another 07 or maybe an 06. I'm wanting the best MPG I can get and still need the power. What kind of things should I look for and look out for? My armada lasted a long time with no problems, but it finally started having transmission issues, and it took 2 years to sell and I took a HUGE loss. I'm trying to make sure I get a good LR3 and I don't want to over look things. I do go off road at times, not really crazy stuff but enough that 4WD is needed. Trails for hunting and stuff like that. Just let me know your thoughts. I need Pros and Cons. Thanks.
