hi,

this question was asked in 2008 but i think this will help someone who is still searching for car export answers. I have recently exported my car from Qatar to UAE by http://www.cartowingdubai.com

You need following docs to export to UAE

1. Export certificate from the traffic department

2. if car is less than 2 years old: you need to get Makasa (customs statistical report from customs in Doha0

3. Power of attorney for the transport/shipping company, attested by Justice department in Doha, which is near to the City Center

Cost depends on shipping company. But i was satisfied with these guys.
