I got a deal at Bravo rent a car a while back. 2,950 aed for a 458 for the day. Hacked it to Abu Dhabi and back with a mate. Was a right laugh. They did a deal. Call direct and see what you can negotiate.
Like the idea of something interesting for the day, but maybe I've become cynical here now as I can imagine getting 100 yards from the place and being stuffed for a huge bill when the clutch goes or something..
