Salam,
If its Punjab Registered & LIFE TIME TOKEN has already been paid then U will just have to spend PKR.1700 out of which PKR.1200 is the transfer fee & PKR.500 is the NEW REGISTRATION BOOK CHARGES (ONE PAGER). Your friend whom u hv bought this car will give u a T.O.Form issued by a GPO or Exice Office which will cost PKR.300. Just go to ETO with this T.O.Form & Registration Book. Better to take the seller also alongwith u. If LIFE TIME TAX is not yet been paid, then u will hv to pay it first. LIFE TIME TOKEN FEE is PKR.10000. THE amount of receipts of tax paid in last 5-6 years in punjab will be deducted from this Rs.10000 & rest will hv to be paid either by u or ur friend i.e. The Seller.
