My car gets about 30 mpg highway and 18 mpg in town. It is a 4-door sedan with a decent space in the trunk, in lovely condition, tires new within the last year, black-grey in color paint job, tinted windows, clean inside, and has a nice after-market sound system (so, yes, you will be able to plug in your whatever iPod, Droid, mp3 player etc you have).
I also have a SWEET up-to-date Magellan GPS that will come with the car - you will never get lost, AGAIN! I've used apps on my smartphone and but my Magellan wins every time.
UPDATE: I just installed an UltraGauge! This means you will be able to check out the car's data, etc while driving. For example, the UltraGauge displays current MPG while you're driving, overall average MPG, how long you can drive until the tank is empty, and other cool tidbits of knowledge.
