i am semi-retired. i live on an island. yet in 6 months i put over ten thousand miles on my 2014 Prius c One !!! this car is a wonderful car to drive. and my mileage is consistently over 50mpg. the stock Turanza tires are wonderful and safe even in torrential rain. just keep them pumped up at 44psi on all four. for me the car handles perfectly that way.
Glad you've come to enjoy your Prius, as I seem to remember threads in the past which seemed to suggest a level of dissatisfaction.
