Doggie,
I don't like salespeople. They really know nothing about the vehicles, I've stood in front a running vehicle with a hard miss and a check engine light and had the salesperson tell me that it runs great and strong. And it's only a little rough at idle. I miss CA, they can't sell a car without a smog certificate, or that is unsafe to drive.
Here in AL, TN and GA they sell them barely running, check engine lights, no brakes, bad tires, 4 completely different tires, sometimes not even all the same size. They'll make them look spiffy on the outside, no dents, shiny, some even detail the inside and make them look as if they've never been driven and spray the inside with "new car" smelly stuff, but safety isn't one of the things they are concerned about. Nor do they care if the car will actually get you home from their lot. One dealer tried to sell me a Honda Element running on 2 cylinders, that they left "idle" (at 1500 rpm, they turned up the idle speed so it wouldn't die at idle) in the parking lot, as I was driving away the thing went up in a cloud of smoke..
I think someone needs to pay us to do used car mystery shops.. for the greater good.
