Ijust turned 18, an i want to apply for a car loan. but as we all know, i don't have credit. i was think of having my mom co sign an all that but she doesn't have the best credit, does anyone know exactly how that would work? would they also require you to put money down?

Yes, most of the time, the loaners (i.e banks) would look at your credit history to see if you pay all your loans on time and in the full amount. Most of the time, they wouldn't give loans to people that have poor credit or no credit, because they either know you will have a hard time paying back, or they don't know if you are able to pay back or not. Many car dealers would want you to place an out-of-pocket on-the-spot payment, and you can pay the rest monthly for the next couple of years. So it would be best to first get a good history of credit card (literally get a credit card and pay your payments on time) and then try to op for a used car. When both your credit history and driving history is good, then you can try to apply for a car loan (and most likely they would give it to you) hope this helps
