I have had the experince of working with two mechanics Sajid (in FB area near Cafe Pyala) and Wajid (Gulshan e Iqbal Block 5). Sajid's ustad was known to be one of the most knowledgeable and expert persons in VW and have heard that had even got training in germany. Whereas Wajid had started from Syed's workshop. after having bad experiences with people like Zareef (lalukhait) and rahim, I found these to be quite reasonable in attitude as well as in expertese. All the mechanics have some tendency to rip off and one should never put blind faith on anyone, however, these two guys are reasonably honest. Wajid is good enough to discuss the problems in as much detail as you wanna go. He overhauled my 1303 engine and front suspension/steering system right at my home.
