Swap history

yet another time waster, he wanted to swop i said yes he then went on to we/buy anycar .com,to get there price of what a car is worth, every body knows, that they offer no money at all, for any car, if you had a £5000 car they would offer you peanuts. £1500/1750 if you were lucky. why do people offer deals if they dont want to swop. then he text at 5.30am, to tell me, and then wont pick up the phone when i phone him later.
