The search for a new car

[elSicomoro]

I've had enough of my stupid car (2003 Chevy Malibu), so I'm getting rid of it and getting a new (or newer) one. I have about 1-2 weeks to get one, so unfortunately, I can't be as selective as I would like. And so, I'd like my Cellar peeps to help. Here are my criteria:

--2002-2007
--Must be durable: I deliver pizzas (for at least the next 6 months) and like to drive a lot.
--Must be dependable: I've had my Malibu in the shop 3 times in 2007 alone for stupid shit. I want to be able to drive it and not have it break down a lot.
--Must be comfortable: I'm over 300 lbs...I need some room. Plus I sit in the car a lot. The Malibu's seats suck...the ones in my fucking Geo Metro were better.
--Price range: >$22,000
--Decent gas mileage: The Malibu normally gets 23/30...a little less would be fine.
--Import or American doesn't matter, though I'd prefer to stay away from Mitsubishis.

Any help or input would be appreciated.
