The Present owner of the Car cannot Sell the Car without paying the Traffic fines if any!!! I Adviced you better to have an agreement between you and the owner, if any Traffic Violations may incurred during his ownership not recorded yet in Traffic department he should pay. It happends to me three years ago, I bought a Honda Civic, When I bought the Car there is no violations, six months after, when I am renewing my Driver licence, the staff in counter told me i should pay the traffic violation first then I can renew my licence. After my explanation they told me to go to Radar section to get a photo. The Staff give me a photograph of the Car, it was Wrong Parking violation at the Airport the date was one year before my ownership.
