Yes, given that the car was a lease, the buyer insisted that he directly wanted to pay honda.. he made it sound like he was not sure of paying me directly.. Well it did not occur to me as an out of the ordinary request at the time.. he wanted to speak to honda and make sure he sent money directly to them..
