It's quite often that people feel frustrated in buying  new cars.  How to get the best bang out of the bucks is a touch  question.  To help you on this, I am listing a few tactics for your  reference.  Remember there are more things to bargain than price alone.  Ask for free oil changes, or maybe include an extended warranty. Make a  rule to "sleep on it" and come back tomorrow before you sign.
1) Learn to flinch.
The  flinch is one of the oldest negotiation tactics but one of the least  used. A flinch is a visible reaction to an offer or price. The objective  of this negotiation tactic is to make the other people feel  uncomfortable about the offer they presented. Here is an example of how  it works.
A supplier quotes a price for a specific service.  Flinching means you respond by exclaiming, "You want how much?!?!" You  must appear shocked and surprised that they could be bold enough to  request that figure. Unless the other person is a well seasoned  negotiator, they will respond in one of two ways; a) they will become  very uncomfortable and begin to try to rationalize their price, b) they  will offer an immediate concession.
2) Recognize that people often ask for more than they expect to get.
This means you need to resist the temptation to automatically concess your asking. 
3) The person with the most information usually does better.
You  need to learn as much as possible about the car you are interested in.  Ask your sales person technical questions on features, comparing that to  other brands'so make him know you are not coming for this brand only.
4) Practice at every opportunity.
Most  people hesitate to negotiate because they lack the confidence. Develop  this confidence by negotiating more frequently. Ask for discounts from  your suppliers. As a consumer, develop the habit of asking for a price  break whenever you buy from a retail store where appropriate.
Be  pleasant and persistent but not demanding. Condition yourself to  negotiate at every opportunity will help you become more comfortable,  confident and successful.
5) Maintain your walk away power.
It  is better to walk away from a sale rather than make too large a  concession or give a deep discount to your asking. Please be aware that  the salespeople is more eager to make the deal with you than other way  around, particularly when in the midst of a sales slump or slow sales  period.
Negotiating is a way of life in some cultures, and most  people negotiate in some way almost every day, China is one. Apply these  negotiation strategies and you will notice a different result almost  immediately.
Good luck!
