Al Tariq automobiles at the qatar decoration end of Midmac flyover,and Al Tadamon motors at Ain Khalid are the authorised dealers for toyota and they both are on the right hand side of salwa road going from midmac to salwa.Both of them source their vehicles from Abdalla Abdulghani but there prices are lower then the main dealer if you bargain hard.The main dealer will not lower prices unless it has special promotion or during Ramadan etc.
