If you can live with the fuel economy, I'd pick up an RX-8 over any of the econoboxes or hot hatches you've listed. It's a true rwd, four seat GT car, and it will hold a suprising amount of stuff.
If you need more space, I'd go for a Mazdaspeed3. How can you go wring with 250 hp and 280 lb-ft of torque in a lightweight car with plenty of storage space? You should be able to get into any new RX-8 or MS3 for $25k or less (substantially less, if you opt for a lightly optioned leftover '. You'll also qualify for S Plan prices on any Mazda.
Also, if you want a "sleeper" 4-door sedan with a lot of power and awd, why not look at a Subaru Legacy GT or a Mazdaspeed6? I drove a 'speed6 and liked it a lot, but apparently I'm in the minority, since they are selling slowly and Mazda is offering ridiculous discounts on it.
