Excellent all the way around
 I've driven mine across the country and it's superb in all respects -- fun, reliable, great gas mileage, great performance, all ways.  Even though it's small, it has good storage space and excellent driving compartment space.  Gas mileage on the road is 34-38 mpg.  Semi-auto transmission is fun, but jerks on changes often, annoying.  All in all, a plus, though.  I'd buy another without question.
