I feel this post should be stickied. Here is info which is missing in other stickies, but these sites help people do their own research on main points which kept coming up in questions. Didn't want it to get lost in another thread.
If incoming expats want to figure out cost of living in Dubai, they can visit the following websites:

New car prices:

(Not self-promoting. It really is the only semi-accurate online guide. The rest are BS)
(A three-year lease totally costs about the same as the new car price, so in general, divide new car costs by 36 to get monthly rate)
Used car prices:
http://www.dubizzle.com
http://gulfnews.com/classifieds/classif ... Sale/Cars/
http://gulfnews.com/classifieds/classif ... el_Drives/
(There are other sites, but all advertise overpriced used car dealer nonsense. Use the above as reference for market rates)
Schools:
Here are the two extremes in terms of price:
Arab Unity School

GEMS World School

(Either one will get your kid into Harvard. No lie)
If anyone would like to add to this list, go ahead.
