Have you ever gone to buy a car yourself? If yes, then you must have noticed few things about the salesman which appear to pretend as if they have knowledge of everything and you are just another dumb guy who does not know much about automobiles.
The duty appointed to the salesmen is that they have to lure the customers into their magical words about the car you are going to buy. They start tempting you so that you could not think about any different thing at that moment.
That will only tell u about the pros and benefits of the car without mentioning its possible cons.
