Oh selling cars seems like it'd be pretty shit in this economy even if you're good at it.
Like most of these shows, they aren't. And the owners are basically ignorant or have given up.
The episode from the week before the guy had hired like eight women or something to be "hostesses" whose only job were to sit in the front, greet customers and give them what was basically a powerpoint presentation. Then turn them over to one of the two or three male salespeople if they wanted to buy a car. The girls had no training or anything so they couldn't even answer questions about any of the cars or knew if they had it on the lot.
At like half of these people don't even know about the concept of "prospecting." They just seem to think they can set cars out and people will come in and buy them at asking price.
