Car buying skills

Car buying skills

I am a total car buying moron so this is where you come in. Please?! I owe around $8,000. for my car. Kbb value for a trade-in is around $5,000. So if I bought a car that they were selling for 10k I'd obviously wind up paying 13k, right? What should I know or do to get me a newer car and a better rate? I know the stern attitude and willing to walk will get them to negotiate but anything else?
