Defiantly a jerk. you payed top dollar too.
funny thing is that i did something similar to the guy that bought my old 2000 but he beat me up on the price what was super low to begin with and at the end when the money was being counted there was another hundred short. I had the Corbin on it and wasn't giving that up and the new bike was still in transit and was going to give the seat that was on the new bike and told him that i would ship it but after all the crap i never sent the seat and wouldn't answer his calls.
