Vehicle was on warranty but dealership tried to not honor the repair. Rather than repairing dealership offered to buyback vehicle. Per the legal parameters of a buyback formula they paid me the cash value of what I paid for the vehicle minus a calculation of the mileage I drove the vehicle since owning it. Therefore, they paid me slightly less this year than I paid over the last several years for the vehicle. It is a personal vehicle. I believe I don't need to claim any of this money paid to me since it was less than I paid and the vehicle is personal. Correct?
