Advice for haggling on a used car?

[SuitedSixes]

Is there an accepted "standard" for price below sticker to start at?

"I'm going to buy a used car today"......this is a poor mindset if you want to save money. tell yourself (and the dealer) that you have time to make a decision, and that only the best deal will make you want to purchase today.

Find out the trade-in, private party, and retail (sticker) prices. (low-med-high, respectively.) Use kbb.com and/or edmunds.com. Trade-in value should give you a rough idea of what the dealer paid for the car, so you can go from there.
