being a car salesman you are right and wrong...
nothing, and I mean nothing good ever comes from a customer going home to "sleep" on it.
the reason being is, buying a car is in general, usually not a very logical decision. It's not rational. If you have a car that runs, you really don't need anohter. YOu may WANT one, you don't need it.
It's not like buying a house or stock or anything like that... it's not an investment, it's a liabaility.
You have to understand, I feed myself, pay my apartment bill, car note, put money in savings, etc buy selling. I am going to do everything I can to sell you a car while you are here (and I can tell you were dealing with a weak salesman or manager, becuase if you liked the car that much you would have at the very least taken the car home if you were dealing with me). not necessarly high pressure... some people you have to assert pressure with, most you have to nudge (like yourself) and some you have to give them a negative close. if i am getting jerked around, I will assert pressure... i will never, and have never let 700 bucks in trade value come between a car deal and me.
you don't know how many times I have seen people not know when to shut a customer down and they try to play the nice guy and let him take his dear time, only for him to come back a couple days later.. "sorry, bought somewhere else"... there is no prize for second place in sales... I had a customer literarly jerk me around for 2 weeks after buying a car for absolutly nothing other than she didn't tell me she was engaged and she bought the car and her fiancee didn't want the car... he threanted me, she threanted me, he told me we better take the car back "or else", etc.. I told her to cut me a 600 dollar check and we will be happy to take the car back (my comission on the deal) becuase i have delt with you for about 15 hours in all now, if not more, and I have to make a living one way or another.....
what i am getting at is, there is no base salary in sales, no second place, you have to irriate people sometimes to get at the real objection to close a deal.. we are both looking at the best thing, and if I don't have what you want I don't want you to buy anything, but it's about uncovering the objection
