Try to resell if the car is working and other documents are still valid. If you decide to scrap it off then remember to do so at a reliable place with full information of the scrap dealer, workshop etc. Generally, they dismantle the complete car in front of the owner and hand over the piece where chassis number and engine number are engraved. Even if they do not, insist them until you are satisfied and have enough of proof that the car has been entirely scrapped off. I’m not sure about the exact RTO Process. Just shoot them a mail and see what they have to answer.
