Each Middle-Eastern state has a Toyota model at #1, and in the case of Bahrain, the Toyota Yaris Sedan and Camry should fight it out for the first place, followed by the Corolla and Nissan Tiida. Other models that could also slip into the Top 10 include the Honda Accord, Toyota Land Cruiser, Hiace and Hilux, Nissan Altima and Isuzu D-Max.
This is a very rough speculation based on the observation of the streets of Bahrain through recent YouTube videos. Please get in touch if you have any more info!
