He told you he wanted it 90% in the first phone conversation and then called and confirmed making arrangements to meet up with you and purchase the wheel. I would call that 100%. Even a phone call would have been a courteous gesture as you had a deal already on the table. I don't want to reduce this thread to name calling and immaturity so you can call your wingman off ok.
As for M50E30- i Don't recall you having anything to do with this and you have no idea as to the situation at hand and the arrangments that were made. Your immature comments are not appreciated nor are they appropriate.
