Annoying sellers

I'm in CL HELL right now. I've sold a mustang at least 12 times already. Only problem is I've been blown off 12 times. People think you have nothing to do but hang around waiting for no shows. It pisses me off! And of coarse they think a $1000 car can slap a plate on it and drive to CA. When I buy or sell something I'm on the ball. Buyer gets the goods the seller gets the cash and it's a done deal. No BS needed. I'm going to look at a car tomorrow. I'm going back and forth. Do I rent a trailer or drive out over an hour just to go back again with a trailer? If it's as good as it looks and sounds I would like to do the deal and be done with it.
