2001 Toyota Prius 4dr Sedan (1.5L 4cyl gas/electric hybrid CVT)
The Prius is a gas to drive, but doesn't need much gas. It has deceptively good pickup for such a small car. During the spring and fall I've been getting over 50mpg, that drops down to about 48 when I have to use the AC in the summer or when I make short trips in the winter and require long warmups.
I love the center screen display that shows you what the car is doing and its performance. And of course the gas mileage.
Better front cupholders. I'd like to have seen some other factory options like leather interior and sunroof.
