good website to buy used cars?

I check out my local craigslist. You can reach the site at craigslist.org and select your city. I’ve bought my last 2 cars from there and it’s primarily comprised of private sellers. If you buy from a private seller you don’t have to pay tax/doc fees that the dealerships charge, nor do you have to worry about dealerships leeching you for everything they can. (I have worked at a couple, I know what goes on) I simply research the Kelly Blue Book value, note what the car is worth in excellent, good, fair or poor condition and negotiate from there. Keep in mind when you look for a used vehicle from a private seller to look over the car with a fine toothed comb and ask for maintenance records or get a carfax.
