2003 Toyota Prius 4dr Sedan (1.5L 4cyl gas/electric hybrid CVT)
Enjoyable to drive with plenty of pickup and great turning radius. At ~50 MPG real milage (a bit higher in summer and lower in winter) you have to love passing the gas pumps. Even after ~500 miles I seldom put more than 10 gallons in per fill up. Works to climb the Colorado hills, but still holds it's own. 'B' actually comes in handy decending on grades. I love my Prius so much I just put a deposit on the soon to be released hybrid-Highlander. Narrow tires cause some handling issues on grooved asphault.
Gotta be the gas milage, but it's still fun to drive.
2003 model had some design issues addressed in the '04 models. Would prefer higher grade interior (leather,...)
