I am 21, I have little to no established credit. I also don't have any family members who have good enough credit to cosign. I really want a new car so I can build my credit and I really need a new car lol. I am looking for a car anywhere between 11-15000. I've heard that if you don't have a co signer you can just put a big sum of money down and that will qualify you. About how much is the normal amount to be expected to put down, with no credit history and no cosigner?
