in 2017 i purposely took transit stop in UAE while returning from an overseas training. Purpose was to visit scrap yards and automotive parts market to assess parts availability of construction vehicles and trucks.
Sharjah Industrial area has every kind of parts from construction vehicles to luxury suv and high end cars spread across 2 sq kms
you must know what you need with model, brand make of item. otherwise every yard owner is 5 times 'cunning & clever ' then a scammer cheater con operator in Pakistan. Generalized requirement can be shoved down your cart with confidence ' it will fit, it will work ' statements with highly lucrative price.
