I'm looking at getting a new sedan, most likely a 4 door and am looking somewhere between 13-20k and am wondering if you all have any suggestions for a good sedan with a BIG trunk. That's a big priority. I need it to fit my fishing gear when I'm not driving the big SUV, and I need to be able to hold a few golf clubs and what not...Space back there is a big issue.

Anyone have any suggestions for a good sedan? Audi, Acura, Honda, Saab, ...???
I'm just in the browsing process now but want something that has good gas mileage, is comfortable for folks in the back and has some good space in it...4wd would be nice...
