Better fuel economy than a hybrid!
 I get 40-41 MPG, mostly freeway commuting.  Zippy and fun to drive around town, but not a great ride on the freeway (the car is very light and doesn't seem to hug the road well at high speeds).  Definitely go for the manual - you'll get a lot more juice out of it AND better gas mileage.  I test drove the automatic, and it was sluggish.  The base car comes pretty stripped of amenities, but that's probably why the car is so low priced. I put a simple spoiler on mine, and I think it really helps the style.
