carbuyingtips is one of the greatest sites on the whole web.
with that said, you ain't gonna get any new japanese car for 7000-10000 bucks.
And may I ask why you want Japanese, I'm not saying that's a bad way to go, just that there is a good counter point to the japanese only arguement.
You can buy an equivalent american car for much less than a japanese car (IE Taurus is a lot cheaper than Camry or Accord) you will probably have more repair problems with the American car, however the repairs will be much cheaper. You will be paying mucho denero if something bad happens to your japanese car.
You can buy warrantees that cover a TON of stuff for like 1000 bucks for your american car too, carbuyingtips has a lot of info on that.
