2004 Toyota Prius Hatchback 4dr Hatchback (1.5L 4cyl CVT)
A Great Vehicle
 I just crossed 130K with my Prius and it will be five years old next month.  I had done nothing but buy tires and change oil for first 100K.  Then I had a rear wheel bearing and now a recent inverter fluid pump.  No big deal for 130K.  I almost always average over 50 MPG, for life of vehicle probably 51. 53/54 in spring and fall and 50 in winter.  I've had maybe 10 tanks less than 50 almost all in the winter and they were usually 48-49.  I am not an aggressive driver and I keep it under 70.  I commute 30 miles each way each day with about 16 miles on the highway avg about 67.  I can beat cruise control on the Prius on long trips by using the hills to my advantage. Over 70 big loss of MPG.
