Did you really lock one of your old threads just so you can start a new thread about more-or-less the exact same topic?
$10k can get you a lot of different kinds of cars. What are you looking for? What do you need it to do? How many doors do you want? Even a country? Are you still looking for Japanese cars? You need to give more information than that if you want any help. With that little description, you might as well go on Craigslist and look for anything under $10k.
