They're going to put up a front where if you try getting like 1 grand off, they offer like $200 off. Don't fall for this shit as they're trying to maximize profit. Last year about this time my father showed me exactly what I'm telling you. He already knew what car he was going to buy, but brought me to multiple places to show how well he can get a price down. Ill make a list oh what he told me.
1.) Don't ever pay sticker, negotiate till they won't go down anymore.
2.) salesman can be pushy, so be pushy back. Show interest in multiple cars the first time you show up
3.)Show up multiple times looking at the same car, show interest but NOT commitment, the less convinced you look the more they're willing to knock off to have you buy the car today.
3.)Bring a mechanic the last time to find any flaws on the car the dealer is trying to hid, and point them out in front of him including things like tire balding and noticeable things that the everyday person can see, it will lower the price
4.) Offer all cash.
5.) If your not desperate wait to do the final offer you'll give for a week or weekend where the weather is bad. When the weather is bad they are not selling as many cars and are willing to lose a little to gain some sort of profit for the time span.
6.) If they don't accept the last offer you give on your second - third time looking at it, hand them a card with your name and number on it. Also the vehicle your looking at.
7.) If they are NOT budging much at all then simply leave the lot and look for a car somewhere else. Never fully commit to a car until it's inspected with a clean title and a trusted mechanics opinion.
8.) do some research on the car you want before looking around. find common issues and approximate the mileage where the problem occurs. Then when you look you can ask questions about it, and find out if the dealer is knowledgeable in the vehicle or simply just bought the vehicle for cheap at an action and is trying to make a quick flip.
We bought a 2000 Buick Regal last year doing these things, sticker price was $4900, We worked it all the way down to $4000 including all fee's for transferring titles, and we got tabs included with it. If you think about it that's like 20% off sticker which is a great deal.
Hope I helped. I just hate how shady some places/people can be to get more money.
EDIT: there's even more things you can do. These are just main ones i remember. SORRY IT'S NOT IN A ORGANIZED MANOR.
