Just FYI, visited there yesterday. I wasn't overly impressed. Lots of cars but felt like I was seeing the same car over and over and over again (If you want a silver Avante this is the place to go). Prices didn't seem any better than what I saw here in Amman, plus a good bit of the cars had stereo systems etc removed, were dirty, etc. A lot of cars that came from the U.S. Were bought as salvage total loss vehicles and repaired or being repaired here, but the final price was not that good for a salvage titled vehicle IMHO.
One guy even told my husband we shouldn't bother buying me a nice car because I'm probably just going to wreck it anyway. Not sure if his reasoning was because I'm foreign, a woman, blonde, combination of all the above, but I found it a bit insulting none the less.
My evaluation -- if you are able to buy a tax free car it's probably worth it as there are a lot of cars to choose from. If you are like me and are not tax exempt, it's probably worth a look (maybe not when its 104°) but don't expect to be blown away by good deals.
