Since he already sold it and we agree it was a scam, I will hyjack a little with a story. I sold a car a few years back for $6000. The lady gave me $3000 and said she would be back with the rest in a couple days. I insisted that I give her a receipt. Even got my neighbor to witness it. 2 days later she and her boyfriend stop by and hand me the money in an envelope. Said they would get the car in a couple days. They were in a "hurry" and left . Well I counted the money and was short $500. Went to the phone and could not find her. Left several messages. Finally left one and said come get the car or the $5500. Well that worked. She showed up saying their was $3000 in the envelope. I said why are you trying to pull this. I said it was only $2500 and she should be glad I had not called the cops. She called her boyfriend and he showed up. Said they wanted their money and why was I doing this. I said alright let me go and get it. Brought them the original $3000. They were like hold on. I asked for them to produce a receipt, because that was all I remembered them giving me. The look on their faces was priceless.I told him go home. I said now do you want the car? Find the rest of the money. Amazingly it had fallen out the envelope into her purse. We finally got the price right and I let her have the car out of pity. She finally apologized and said she got the rest from her dad and it was his idea. Watch out when dealing in cash also. Always make a hand receipt, even before you do the legal papers.
