Im 22, I have a decent job, decent credit, i just graduated with my bachelors and I am in need of a new car. I really want the 2009 Mazda 6 but I don't know if that is a good choice. I have a crappy 1998 Saturn SL2, can i trade that? Is it worth anything? How much should I put down? I just need an economical fun car. I have friends who want to go with me because they think they know about cars. But some say to get a new car because it is a good time to buy... and some say to get a used car because they have lower interest. I don't know what to do, or where to start?! I just don't want to get ripped off. Is there a step by step guide to buying a car?
