I know all the common sense things most people will want to give me advice on...I've bought 3 used cars in my younger years. But now I wanna do it right. Do any of you have experience searching and buying used cars? I don't want to pay the "certified" price being sold at a dealership and I know to carfax when I'm interested. I'd like a simple $4-5K sedan of some sort. Any ideas where to start??? Thanks!
