Help !!!!!!!
Due to arrive in Dubai in Feb / Mar 2015.
Got a proper deal [oil and gas engineer], and am allocated 6500 USD / month for accomodation, utilities and a car.
1. Where do we stay [just my wife and I].
2. What car do I buy. Thinking a Golf GTI as it'll cart pushbikes to the "facilities".

Also, I train triathlon - Assume good poools, etc all available, etc.

HELP !!! All advice appreciated !
