Say No to Add-Ons

Don't let dealer add costly Add-Ons like rust proofing. If you have done a good job at driving down price initially dealer may try to stick it to you with unnecessary Add-Ons or even an undesirable financing package.

Don't Be a Sucker

If you are not good at negotiating with people, bring someone who is. Don't let yourself be a pushover. Always be willing to leave lot if you aren't comfortable. There are other cars just like one you are walking away from. Don't make final decision to purchase car with salesperson present.

Don't Let Salesman Flip The Script

One trick that car salesman try to pull on people is offering different financing when it comes time to sign papers. Never drive a car off lot until all financing is arranged and all papers are signed. The sale is not final until you sign papers.

If you do drive off with your car and they call you back to deal with some details of financing, be very careful to check that you are signing exactly terms you agreed to. If dealer tries to change terms of deal drop keys on desk and leave.

The Federal Trade Commission has a lot of good information about buying a car.

If you are uneasy about decision you are about to make, don't sign papers. Don't worry about car salesman's feelings. Make sure that you leave with a car and are completely content with your decision or you leave with nothing at all. If you have an unsuccessful car buying experience you will be reminded of it every time to drive your car.
