in the middle east, in every country there is only one official dealer for each brand, and Dodge dealers don't have the Viper in thier showroom.
What people do is buy it and ship it from the states, what those dealers do is they give false promises. I registered my name for more than one year and still they didn't bring one car. They also restrict you to the GTS and 25-30 grands mark-up.
Some of the other unofficial after-market dealers bring such "states-registered" cars, but mostly its been the C7 for the availabilty, price, and demand. I've seen few C7s and Gen Vs in my country, Kuwait. But surely nothing beats the UAE on a global level for exclusive cars.
