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.
Mileage; reliability; the car is a commodity. Get what you pay for but not a fun, sporty ride, but that's not what a Prius buyer wants.
Needs DRLs, sun slides on visors, a little better info when there is a problem. Also a little longer dashboard would block reflection of speedometer during night driving.
