my mistake!! the lesson for you!!
well recently I purchased an open-used bike from Lahore I got the original copy and file but I didn't get the sale purchase letter as he was the second owner who didn't transfer the bike on his name and used it the main thing is its original number plates were misplaced and I didn't get them from the second owner now the thing is I am quite worried and kinda suspicious about that bike what if the bike is being used in some kind of illegal activity!!
I am not using it for now... I have no contact with the original owner but I have 2 photocopies of his id card which I got from 2nd owner
so lesson is never to buy an open-used bike with no number plates or fancy number plates!!
2nd if anyone can suggest me any solution please reply!!
