OP, you did not do the right thing in the first case. What you did is against the motor vehicle act. And now in this case, you are requesting what can be considered illegal help on a public forum to do something illegal to cover your mistake. Sort this out yourself, by yourself, deal with the consequences and don't engage anyone in these questionable discussions and behaviours. You may come out clean but someone will bear the consequences of your erratic mistake.
In future, no matter how badly you desire a car, if it cannot be transferred the day of purchase, no deal, no sale and no purchase!
