Bin mahmoud guys do not do denting and painting. You have to go to the industrial area only. Most of the guys in the industrial area do a passable job - what I mean is that their work will pass the technical inspection. It doesnt mean it will pass the owner's quality control !
hmm its a mitsubishi lancer. industrial is very far we werehoping to find something closer. i have seen some car repair shops in bin mahmoud but not sure who is good and whether they have denting and painting facilities.
Option 1 (cheaper)
Go to industrial area - there are many denting/painting workshops in that area. I know one workshop in street no.27
Option 2 (not so cheap)
Or, call up your car dealer and get the location of his workshop. If your car is Honda, you can take it to their showroom and hand it over there. They will take it to their workshop, do the repair and call you when its ready. I am not sure about other makes.
