In my opinion, there is learning process that happens when you go out and get a loan for a vehicle that builds every time you do it. I've met too many grown people that don't know how to do this, and are afraid to even try. It's the little things that add up to being able to buy a house, or land, and become independent.
My parents helped me buy my first vehicle in High School with a $500 loan because I only had a grand saved up at the time. I had an after school job, so it wasn't a huge effort for me to pay them back. After High School, I sold it and joined the Marines.
Once I got settled into life on base, I decided that I wanted to buy a car. It turned out that every dealership, new and used, was more then willing to loan me money to do this. I shopped around, looked at a variety of vehicles before buying, and then went through the process of applying for my very first loan.
