Yes, the person's name is Haroon and he runs some printing press kinda thing on Cooper road,being a car dealer is his second profession. The EXi you've mentioned wasn't mine, mine was sold about 6 months ago - it was an LRA number. A new ad was put up the same day on Pakwheels for 1.25 lac more than I sold it for and I guess it got sold again in a month. I give the whole credit to his selling capabilities - there's nothing wrong or illegal with buying cheap and making profit.
Your case however is different. Since its a legal issue, I am sure you need to contact the authorities and find out if he was the man behind the fake tokens trickery or if it was the previous owner.
