Still got 7 yrs left on hybrid warrantty. Even if it goes out I'm sure I can replace it for few hundred. Or I can swap out bad cells for less than $100. I've done timing belt service and just yesterday replaced clutch on my Z so I'm confident I can do work like this. I will keep this car until literally wheels fall out. There are cabs and older prii with 200K+ miles on original battery. Besides for $20K my options are limited on stripped models. My prius is loaded with BT, nav, solar roof, sunroof, leather, heated seats etc
