If you’re reading this article, you are savvy enough to look for information before you undergo the root-canal procedure known as car buying. If you are the type of person who can keep an open mind and maintain focus on the details, you should be able to use this information to quell any potential pains in the process.
(1) Eat Before You Go

Eat. A car deal can take a long time to complete. Even those who pride themselves on being able to get in and out of a dealership can often run into the unforeseeable roadblock of waiting to get into finance to finalize the deal. A pleasant meal before embarking can eliminate a potentially unpleasant factor in the process.

Call ahead and ask point blank, “I really want an honest, pleasant salesperson to work with me. If you were buying a car, who would you want to buy it from?”
(3) Bring Donuts

Bringing donuts sets the tone. You will be instantly liked, not only by your salesperson, but everyone who indulges in your treats. It sounds insane, but when it comes down to those final negotiating dollars and cents, a considerate customer will receive more consideration from the dealership.
(4) Prepare to Make a Day of It

If you set aside a full day and start early, there won’t be any time constraints that can ruin a car deal. At busier dealers like Orange County Toyota Dealers, you don't want to be rushed by poor scheduling. If you are able to wrap it up in 3 hours, that’s more time for the mall, golfing, or showing your new ride to friends and family. If it turns into an 8-hour day, at least you were prepared for it.
It happens every day. Someone goes to a dealership, finds a car, starts to negotiate, but has to leave for one reason or another. The next day, the car is gone. They can get mad, but the reality is that people regularly promise to come back the next day and never show. Unless they put a deposit down, most vehicles cannot be held.

Set your phone to silent. If you can’t, make sure the office and everyone else knows to only call for emergencies. Treat buying a car as if it is something important. That shouldn’t be hard – it IS important.
(6) Take a Long Test Drive
Take it home or to a parking lot where you can get out, look it over thoroughly, and decide if you can picture yourself in it.
Whatever you do, don’t make a large purchase like buying a vehicle without an extended test drive first.
(7) Use a Lifeline

Have someone available by a computer to look up anything you need to know. If you’ve found a used vehicle you like, have someone look it up with a large search radius on Richmond Used Cars or other local internet dealer listings.
For new cars, you should know all of the information before going to the dealership because you…
(8) Work the Internet First

In some dealerships, the internet department is made up of salespeople. In others, like Oklahoma City Ford Trucks, the departments have Customer Resource Specialists, Business Development Operators, or one of a plethora of colorfully-titled, non-commissioned representatives to do research and get you the best prices.
The first thing you should ask when starting a dialogue with an internet department is whether or not they will be the salesperson assisting you. If not, you are probably dealing with a salaried employee who makes a bonus if you buy but who doesn’t make a percentage of the gross profit.
In other words, they get paid if you buy regardless of the profit, and thus will work harder to lower the price for you.
You have an opportunity to cut through much of the red tape and get straight to the price with a true internet coordinator. If they are commissioned salespeople, then you might as well refer back to “Ask the Receptionist” before deciding to work with them or not.
(9) Trust Your Gut

If you have a strong negative feeling about the car deal, chances are you haven’t found the right vehicle, haven’t gotten the best deal, or didn’t bring enough donuts.
(9.5) Enjoy the Experience

The line is nearly as ridiculous as someone saying, “Have fun buying a car!” Still, I will say it with feeling.
It doesn’t have to be bad. The dark ages of car buying (1978-1997) are all but gone, thanks tremendously to the internet. Many of the sleazy salesmen of yore have withered to selling furniture, vacuum cleaners, or real estate. Those who are left have been reprimanded often enough by an informed public and therefore have reluctantly adapted.
There are still bad ones out there, but not nearly in the bulk that existed before. An old- line salespeople used to use when getting caught asking for full sticker on a vehicle went like this:
“I didn’t think you were a fool, but if you were, I didn’t want to miss you!”
Thanks to the internet, many dealers start off discounting a car before the customer asks for it. The old line has been replaced by one that is more relevant in today’s competitive car market:
“You may not have checked it out online, but if you did, I didn’t want to insult you.”
Special thanks goes to Al Gore for inventing the internet.
I hope it helps.
