Finding one is not an Issue but mustangs are high fuel consumption cars, can you afford it. You can find some at Wagib Automobiles Section , Check some at http://www.wagib.com/automobiles/ford/mustang .
If the problem is in its outer look like body or front look than i suggest you to make some graphics work on it. It is the less expensive process and your car will look awesome.
You can order it directly from the USA from the Auto Auctions they have their for cheap! you will just need a car Shipper. Ive used Vessel-Shipping.com for how to ship a car, Car shipping to Dubai.
