There is the Lemon Law on a new car. On a used car there is the law of serviceability. The car must be serviceable. In other words it must do what a car is supposed to do. Get you from point A to point B. It also depends if the used car has a warranty or you bought it "As Is". On an "As Is" purchase, you have few rights other than serviceability.
A person who sells cars is called a Car Dealer. There are many names for someone who sells cars. The Title "Car Salesman" is one of the more polite ones that come to mind....lol.

Do you have the title of the car in your name? Is there a loan on the car? You will have to register it if your name is on the title!
You can find a car dealer that sells new cars by looking at some online websites that show cars from various dealers. A really good example of one of these sites in AutoTrader.
