I like my 2000 Nissan Sentra. 5 spd, alloy, preminum sound, with 38k I paid $7500. Great car. Not great handling, but fast enough to get into trouble. 51k and not a thing done to it save oil changes.
When I do buy a new car, though (which won't be soon--I'll have the Sentra until it won't go forward anymore), I will hands down not buy foreign. You're just not getting what you pay for IMHO. If I had to buy a car today, and..
my price was x: I'd buy y
$30k: Pontiac GTO, Ford Mustang GT convertable,
$20k: Ford Mustang, Pontiac Solstice (fantastic looking car!), Ford F-150, Ford Fusion, Pontiac G6, Chevy Colorado, GMC Canyon.
$15k: Ford ranger, Pontiac G5
I would not buy used, but that's just where I am in my life. I want something new. For under $15,000, I'd probably buy a used Japanese car, too.
*The only foreign car I'd consider is the Mazda MX5 Miata, because I think that car looks stunningly nice.*
Best of luck!

edit// DO try a Mazda; every test drive I've ever taken with one I have laughed hysterically the entire time. "Zoom zoom" is for real, they are FUN cars!
