When getting a major $$ deal on a car

If I'm the seller I try to get the most I can...if I'm the buyer I will go to the mat to get the best price I can. I go into a deal on both sides with a number in mind. I don't sway too far from that number on either side of the deal. It's an art, a dance, be respectful but, try for what works for you. Everybody has a number..seller...buyer...both have a number. I always try to make sure that if I need to unload the car that I wont lose my ***.
