I just bought a 2h car. Traffic was a disaster - 5 trips to complete!!!

You will need the estimara, patience, a fair understanding of arabic, and both parties to the deal. Yes, seller and buyer must turn up together. This I ws told on my 4th trip - a copy of the seller ID & a letter were insufficient. We returned together on the 5th trip, he paid his (previously unmentioned) fines, then, halas!!

You can register an uninsured car, but you cannot insure an unregistered car. Thus, rego first, insurance 2nd.

Good luck.
