The trick is to negotiate down to a decent price and then say the you feel like they are not being reasonable and you are going to shop around. Then just leave. Its hard to walk out but you have to. Don't worry thought bc they will call you back a thousand time since they feel that you are a real buyer who is going to go buy somewhere else. Then when you go back to the same dealership that you walked out of, they will give you a better price. This is where you say that you got an even better deal across town at the other dealership. Then use your discretion about finishing your car deal. Good luck... the hardest part is getting out of there the first tiem
