Buying a car (Dubai)

Hi all,

I want to buy a car but I'm thinking whether I should go for a new car or an used one. And if it's used, what is better between Dubizzle or a Dealer?

I've been told that if used, better to go to Dubizzle but I'm not sure if I can trust some of the announcements there. Anyone has experience in this area? Any tips?

All your comments will be appreciated.

Cheers

Julian
