Yemen 2010: Hilux and Yaris Sedan in command
There are no official car sales figures available for Yemen, so I relied on observation of the main Yemeni cities' streets through YouTube videos. They show that in all likeliness, the Toyota Hilux is the best-selling vehicle in Yemen, followed by the Toyota Yaris Sedan.
Toyota seems to have a strong hold over the Yemeni market with the Land Cruiser and Camry possibly in #3 and #4. The other very successful brand in Yemen is Hyundai which should place the Getz, Sonata and Tucson within the Top 10.
