Okay I just got back from the dealers yesterday and my choices sorta shifted away from the X5 and Murano.
I'm thinking now the new Land Cruiser vs. the new Lexus RX 350.

Look at that beauty!!!!
Both of those cars have the same price tags on them and technologies. However, one's got space, and the other doesn't. I frankly love the space inside the Cruiser. It's good for bringing the mojo into the dojo

I literally opened all the seats and found myself in a king size bed! That's awesome! With tinted windows and lights off, soft music, sparkles.... You just got yourself a 5 star hotel room!
Disadvantages? No AUX out for my mp3 player (Zune), and the size of the car is practically huge which makes it tough to park. Then again there are sensors.
As for the disadvantages of the Lexus RX 350, it's simply small from the inside and it's too low to handle constant driving over sand/mud....
Both brands have amazing service in the UAE and are highly demanded amongst the people here. Which tells you enough that the cars are good.
So... which one should I go for? Oh man it looks like I'm going for the cruiser....
BTW V6 for both. I'm not into speed and also my cash won't help me get a V8 or even spend constantly on fuel for the V8. You can fill up the whole 2 tanks of the cruiser for 150 Dhs and keep running for a week.
