I say tell your "personal reason" that she has to move to Abu Dhabi. A much nicer place to live than Dubai.
My vote is that you buy anything Japanese. If you can afford it a Lexus or an Infiniti, if not a Nissan, Toyota or Honda. They are cheap to fix, they are amazingly reliable, they have decent airconditioning (Unlike most european cars including the Toureg), they actually can go around corners without killing someone (unlike the Chryslers and Dodges) and they keep their resale value better than anything else in the Gulf (unlike all cars mentioned but especially the Yank tanks).
