Sales Advice - Lots f Interested Buyers!

Everybody is a qualified buyer over the phone or on the internet. You wouldn't be the first person to be convinced to turn away qualified buyers waiting on that guy who going to pay you more than anyone else only to find out that person never shows. Or they show up and pick your rig apart and try to negotiate a much lower price. Or they are totally willing to pay an excessive price if you are willing to overlook their past financial difficulties and finance them. Or maybe they just con you out of the rig.
The only answer is first come/first served with cash or easily verifiable financing in place. Don't get greedy, get your price and be thankful.
