there's a shop in bin mahmoud along aljazeera street named "kardef auto electrical". not only they are good, but very honest too. they tell you exactly what's wrong with your car & will charge you the right amount for labor & sometimes, parts at cost. they also do other services like take your car for renewal registration, etc. for regular customers, he arranges rent-a-car while your car is under repair for a minimal fee. the owner's name is mr. kamal & his shop is near badriyah restaurant.
