There is a website call if you contact them they can guide you. It’s not as easy to make money as you might think. It is work, don’t get into it looking to make a fast buck.

i mechanic for a living,and own a shop i went and got my dealers license because i sell a few once in a while,,its fairly easy to get the license,but there’s not that much profit to be made when you first start off, i live in Tennessee also and the insurance is expensive,you also need a building,and a certain sized lot to operate from also,,my first year i spent over 10 grand getting set up,and probably only made around 6 grand from selling cars,you can go to the court house and they can give a business license form to fill out,and then you mail it off ,wait till they contact you,then you have to show proof of a building and lot,i sell out of my other business,and i barely got by like that too,but if you want to do it,,you can make a little money at it,but buy the time you buy a car ,and fix it to sell you,ll find there’s not a lot of money to be made,but you can earn a living from it,,good luck at it.hope this help,s.,happy new years.

You’ll need a TN dealer’s license.
