you cant trust peoples word, give a deposit and get a receipt saying deposit amount, amount still owing, date amount is due, and if deposit is refundable or not ( I dont refund deposits) then get name address and sig of both seller and buyer.
he cant sell it out from under you if you do that.
I have had soo many people call me about a car or something i have for sale on CL. and they ask me to hold it over the phone....First one with the cash gets it. I ussually dont even take deposits anymore either...too much BS. I dont know why people are so undependable. my word is my word. I dont know what so hard about living that way.
