I have a 2005 Prius with close to 130k miles on it, and I love it. It’s been trouble free, just wipers and oil changes, for more than 12 years. Only now do we have our first age-related item, a control module that makes the dash light up.
I would buy another Prius in a heartbeat, though if I were looking now, I would avoid the 2010 - 2014 years because of this problem: https://www.claremonttoyota.com/dealer-initiated-prius-shop-sale.
Here’s another link in case the dealer one doesn’t meet link standards: http://www.latimes.com/local/california/la-fi-toyota-prius-defect-20180207-story.html
