The first time you go to the car dealership is NEVER the right time to buy. This advice is best when you are new car shopping. If you ensure the dealer knows you want to buy the vehicle, going home will strengthen your negotiating position. Within hours, the dealership will make you a better offer. They can't stand letting a car deal get away. So, making them fester a bit will make sure you get the perfect new vehicle at the best price. Congratulations, you win.
