How hard to get a 7000$ loan?

You may not want to hear it but that is the best advice ANYONE can give an 18 year old with a part time job at a fast food restrauant. You alone are NOT going to get a loan for 50 dollars much less 5K. So like it or not and it is the best advice go get a clunker until you can save a lot more money or age with a true full time job of about 2 years to lean on for credit.
