The Prius is a mid-sized car with room for four full sized adults or you can put a bicycle or two in the back without removing the front wheels.
The maintenance costs are low. My 2004 Prius has cost 12 cents per mile for dealer maintenance, tires, and fuel combined over the 125,000 trouble-free miles I've driven it so far, according to the logbook I keep. It still runs like new. So does the 2001 that my wife drives--though she doesn't keep a logbook. Based on the high owner satisfaction ratings, my good experiences are not unique.

The Prius was designed to be a hybrid from the ground up. This compares to some hybrids that are basically a conventional car with an electric motor stuck on to replace flywheel. The Prius has removed many of the parts of a conventional car and replaced them with more reliable electronics and has simplified others. For instance the Prius doesn't have: an alternator, a starter motor, a serpentine belt (2010+ only), a clutch or fluid coupling. In addition the automatic transmission with it's hundreds of parts has been replaced by a simple planetary gear system similar to a differential.
The Prius gets the best mpg. This is especially impressive when you consider that the Prius is a mid-sized car. Other cars, including hybrids, that come even close to the Prius' mpg are much smaller. It doesn't take a rocket scientist to figure out that the smaller you make the car the better the mpg will be.

The Prius has been around the longest. It was first sold in 1996 (1997 model year) so it has the most proven hybrid system.
Once you have driven a Prius for awhile, it will be very hard to go back to driving an old fashioned car.
