If I remember correctly, PakWheels took the initiative of token submission on behalf of vehicle owners in Lahore. I believe that your website has lots of revenue sources and its about time that a service for Karachi be launched. In my opinion, PakWheels should devise a mechanism through which Karachi registered car owners are able to pay their tokens. You can create a service desk in Karachi where people can mail-in their registration docs and get their tokens done with PakWheel's trust. I believe that this service will not only help boost your website's revenue, but also provide a valuable service to your clients. Please look into this matter and see if anything can be done.
