When buying a car remember:

Sellers do not make any money if you WALK AWAY.
NEGOTIATE the PRICE
Banks do not make any money if you decide to WALK AWAY.
NEGOTIATE the INTEREST RATE
Be prepared, shop around, have good credit, everything is NEGOTIABLE.
If you are not happy with the deal, WALK AWAY.  Someone out there wants your money.
