Think of buying a car as a game of poker, the seller is your opponent he may be bluffing he may not, but just as you would at a poker room in a casino you have to try to read the seller like you would in a poker room in a casino. Always remember to keep your eyes and ears open, when talking to someone about a used car. Make sure to ask lots of questions.
In a casino you are risking your money, in hopes of getting a big return, but when buying a car you just want to get your moneys worth, you want a car that will be reliable and dependable.
