2012 Prius C two at dealership

I am on the lookout for a commuter car for my fiance. She is not picky, but likes an economical car. She previously owned multiple Prius. Her last one was a 2001 with 250k+ miles. She gave that car to her brother and recently moved and is going to need a car for work.

We recently came across a 2012 Prius c two with 158000 miles. The car has a Carfax report. Had a moderate accident, but was fully fixed in 2013. Has been serviced every 5k at the same dealership it was bought (and currently for sale) at. 2 different owners, same story. Dealership is very highly rated and did a full inspection including changing all 4 tires, wipers, oil change, etc. The car is clean and in great shape inside and out. We live in Florida and it has been here all of its life as well.

My question is, is it risky buying a 12 year old Prius c with 150k+ mileage with the original hybrid battery? I'm worried we buy it (at the pretty great price they have it listed for), and soon after we have to drop $2k to get a new hybrid battery.

Thoughts? Thank you for the advice!
