So, the buyer is found, the price is negotiated, you can start the deal. First, make sure that the book has at least one free column where you can enter the data of the new owner. If the main document of the car is already filled out, you will have to get a new one from the police. Otherwise, there will be nowhere to reflect the information about the buyer. Moreover, we do not recommend changing the form on your own initiative in advance. The inscription "Duplicate" on the document may scare off a potential buyer, and the sale will be delayed. It is better to show the original, in which the history of the car will be visible. Since many delete vin history for their own benefit.
