Automotive Forums  Where Car Enthusiasts Go to Discuss Cars Online

hello there
as mentioned in title I need to buy a 4x4 car,
now, off road performance is a must.
I have several models in mind, but am really lost about making the right choice of one off them.
Toyota 4Runner, Jeep grand cherokee limited V8, Discovery II, Models between 1997 and 2000.
now I would love to know about best parts availabilities, fuel economies, off road capability, and off course comfort.
If any other is to be applied I wont mind.
So thanks in advance guys.
Right now I own a lada niva 1.6 1991, guess am gonna keep next to the 4x4 am planning to buy, maybe after buying other capable 4x4 I'll change my mind in keeping it  

I would stay far away from the Disco II, that is a money pit and a half.  I would go with the 4 runner for a cross of gas mileage and off-roadability.  Not to mention Toyota reliability.
