Welcome dude!
I feel you on saving up for a car, I wasn't able to get my first car until I was 23. Got my bike a few months before the car. My cousin gave me their old Honda Civic as a gift for free, In turn I was able to pay insurance full for a 6 month premium. My bike on the other hand the guy was moving to Texas an$1d wanted to get it sold a.s.a.p. and wanted $1,800 for the Kawasaki 250, Luckily my buddy was with me and talked him down to $1,250.
So Iv'e been pretty fortunte.
I wish you luck with saving up for a car. Just remember, It dosen't need to be "New" As long as its in good running condition and it gets you from point a to point b don't listen to what people say about how it looks you will just be happy you have wheels.
A pointer for you when looking for a car, check those car magazines they usually have some good deals and ask friends or family to look out for you on a car and have someone that knows a little bit about the mechanics of a car to check it out for you, The worst thing is to get a car and then have to get it fixed unexpectedly.
As a tip for saving up, I set aside 15% of what i made at work and set it aside for a car. What ever you do, Don't touch it even if you have the urge for the newest and greatest video game and want to dip into it and put it back later Don't.
You can calculate this by: Your Earnings - 15% = on your calculator
Hope this helps and welcome to the fourms and good luck!!!!
