Step 4 - Purchasing

Don't be swayed by smooth talk.  Salemen do this multiple times every day!  Stick to what you know.  If something sounds off, take some time and research it.

There almost 14,000,000 cars sold every year.  Avoid FOMO and make a decision on your time frame.  Unless your shopping for something rare, another will come along. 

It's not about taking them for every bit of profit, it's about getting something you are happy with and being treated fairly.  The happiest drivers are not the ones that focus on the best deal ever, but the ones that focus of the best deal for them.  Having a new car should be fun.  

Get everything in writing, employees come and go, people forget things, things fall through the cracks.  "Bring it back next week and we will look at that", "We offer everyone free car washes", "First oil change is free", "Oh, we'll take care of that for you".  Get it in writing.

Look everything over.  Double check the numbers.  It's a big purchase, take your time.

You are the buyer, you have the money and you hold the cards.
