The electrician guy's name is Sabir (03002153016). You can also tell him that your doors need oiling or whatever and he will let you know about the other guy as I cant recall his name. The last I met him was when I got my Lancer's instruments cleaned a couple of months ago, so if you take my name maybe he will recall.
As for the seats you can go to that street on Tariq Road and ask around - there are a few shops there but I got my work done from this guy called Mubashir.
I got the foundation replaced from Drive In. Cant recall the cost but let me tell you the parts of this car are expensive. Per my experience there is barely any difference between the parts cost of this City and a Dewan Lancer. Thats just my personal experience.
