so, if i understood correctly, before we go to the traffic department, the insurance of the car should be changed to the buyer's name.

Also, when does this ready cash get handed over from buyer to seller? Is it .
1. at the time of insurance being changed to the buyer's name.
2. at the traffic department during transfer of istimara .
3. After transfer of ownership and all formalities are completed.

When does the car actually belong to the buyer - when he hands over the cash or after transfer of ownership and insurance is completed ..

Is there something that we should be careful about from unscrupulous ppl, if any?
