Going off your figures you listed in the plan for a daily driver, I think you will have a hard time finding either a WRX, A4, or a Mazda6 for the amount listed as category B. I love all those cars, they just run a touch higher used(being that all new run around 20K+,) I know you can by a base model 6 for cheaper, and maybe find a used one for arond 10K, but what is the fun of a base model?

I would lean towards category C. I have heard good things about the Elantra. Hyuandi is now rated right in line with Toyota and Honda on quality...plus with the warranty it helps. There is also the Mazda3...with this car you can stay within your guidelines, even pretty fully loaded.

If you are going towards category B, I would look at a few of the other imports like Altima, Galant. Those both are good looking cars, although a touch bigger. Maybe even a Subaru Legacy. Those are my suggestions based on figures provided.
