If you plan on flipping a lot of cars to make money, you may want to do some research before you make too many plans because it is technically illegal and if you sell too many cars in your name the DMV will flag you. Every state is different, but you may get flagged in as little as 3 sales. I thought about doing the same thing, but from what I have read so far, it's not easy to get around the laws and most states don't make it easy to get a dealers license.
