If I'm not mistaken, at the end of the video he said how he got the money to buy that prius. He borrowed and made money out of it, so he bought a car from that. So basically, he said he didn't regret buying it because it's like a freebie from his loan.
an item value is very dependent on the buyer. if the buyer says the item has historical value, any item at a price can be very expensive. there is no expensive item if the buyer does not use it. This is only a trade that can be very unique and strange, but this can become a reality.
