well, thanks to Cash for Clunkers - used cars aren't as cheap as they used to be!! That's why sooo many dealers are giving 125% of blue book value for trade ins.
Try craigslist - verify that you can take the car to your mechanic and have it looked over.
Try ebay - there are tons of used cars for sell on ebay.
Try CarMax....there are a lot of places to look. You can even try used car lots...
good luck!
