Others are imported from Iraqi Kurdistan and Georgia, said another Aras auto trader.
There is little doubt about the potential prize on offer. Production by Iran's domestic car industry, unusually developed for the Middle East, peaked at 1.6 million cars in 2011, the year crippling new sanctions were introduced.
Imported cars are taxed heavily in Iran, more than doubling their price to protect its domestic industry, but international brands which are exported to Iran in parts and assembled there are subject to much lighter taxes.
That is the business model of French manufacturers Renault and Peugeot. Both have been active in Iran in recent years, contributing to the production of more than half a million cars in 2011, around a third of Iran's total output that year.
Ever tougher sanctions imposed by the United States and European Union in 2012 have forced them to withdraw from the lucrative partnerships.
But they are hoping for a quick resumption of activities following the initial nuclear deal, which offers a six month suspension on trade sanctions on selected goods including auto parts in return for a curb on key parts of Tehran's nuclear program to allay Western fears it has military aims.
There is little clarity yet on how and when the deal will be implemented but analysts says Iran has the potential to be a profitable and fast-growing auto market exceeding 2 million vehicles annually in the event of a sustained diplomatic thaw.
Even in the best case, that will be some time in the making, but Aras sales manager Mohammad hopes the ban by Iranian authorities on importing U.S. cars to the general market will change much sooner.
