During my studies when I was overseas we had a seminar on how to buy a car in NZ. The guy was absolutely awesome, he told us about a lot of the tricks employed by dealers from subtle things like mirrors where you are supposed to park the car (you see yourself in the mirror) to things like working you with two people (it's much harder to resist 2 people arguing with you, also why you should never go by yourself). He also gave some good tips: go at certain days of the month when they are about to get new stock in, try to find the underperforming salesperson (they get away with worse deals, because the others feel sorry for them), give the impression you are planning to buy for much less than you really want, because they always try to get you over your budget. I managed to use those tricks when I bought my first car. Managed to get it at about 40% of the sticker price (used car). Haven't been as successful since though.
