I had a seller pull that with me last summer, apparently he gave his address to several people saying he had to be at work by 3pm. It was 1:45pm and I was 30 minutes away.
I get there and he's got the bike out in the driveway with someone sitting on it already, and two cars driving up behind me.
I walk over to him and the bike and he tells me to 'wait my turn'
I then ask him if it was some sort of #$%^&* auction?
I made it very clear that I was not there to bid on a bike. The guy and his wife who were looking at the bike scurried away in a big hurry. The seller thinks its funny.
Thinking that if I stuck around it won't end well for the seller, so I just told him where he could shove the bike and I walked away. I stopped and told the other two who showed up what he was up to and one of them left too. So much for his 'bidding' war. I watched the last guy walk over to him, look at the bike, give him the one finger salute and walk away. Later that day he had upped the price on CL from $50 to $350. The bike was probably worth $100-125, nothing special, just a clean old three speed from the 70's. A week later he's got the bike listed in pieces, each piece listed for more than the whole bike was worth. It was listed all last summer with no takers.
I've had a few others pull similar tricks lately, they list something for $50, then want way more when you get there saying the price in the ad either didn't mean anything, or that its just a starting point.
I absolutely refuse to deal with guys like that. If you want an auction, put it on eBay, if you list a price, then sell it for that price and be ready to negotiate if its worth less.
Locally, bikes don't sell well at all, you could list that King Sting for $30 and maybe not even get a single reply on CL. I had an '82 Sidewinder in what I'd call just fair shape that did ride, but it needed lots of tlc. I put it up at $100 figuring someone would haggle it down to $50. It sat listed for nearly two years before some guy finally drove all the way up from Wash DC to buy it. He handed me the $100 and left. He couldn't believe it was still for sale, he said he saw the ad when I first put it up but couldn't find the time to drive the 2 1/2 hrs to get it. He showed up in a VW Beetle convertible and drove home in late Dec with the bike sticking hanging out of the back seat. He was the only person to email about the bike other than a few nonsense emails asking 'Is this still available".
