how much do you get approve for

Depends on a lot of things. Credit, type of car, type of dealership, and finance company. I would suggest going to a bank or credit union (your own if possible)to get financed before you go to the car lot this way the car lot can’t screw you on interest. Once you get your approval amount you can go to the dealership and negotiate on your terms, because you know what you have to spend. Next pick a dealership that provides warranty on its vehicles, so that you are sure any problems that may occur will be fixed through the warranty. Hope this helps.
