High Mileage Gen 4 Prius Opinion

I am looking at a 2017 Prius (Option/Package 2) and it is high mileage (sitting at 198,000 to be exact). The price, however, does seem to fall within the Kelly Blue Book range, however, the place selling the car has no knowledge of the cars prior history whether if the hybrid battery, or engine ever were serviced/replaced. Now, I have purchased high mileage (And I mean, super high mileage!) Prius's in the past, but I was comfortable doing so because I have ODB2 + Torque + Dr Prius along with Techstream to do my due diligence of testing, and overall telling if the car is in shape. I assume Techstream with the generic Mongoose cable can pick up any inconsistencies or codes?

Aditionally, from my research thus far, it seems the engine changes a bit in this Prius, and the hybrid battery changes as well. I was therefore wondering, is there a consensus on how reliable the Gen4 Prius is whether it is related to the engine or hybrid battery? For example, 2010-2011 was notoroius for head gasket issues and some had weird issues with headlights consensating, etc... Any chance this kind of issues exist with the Gen4, or at least the 2017 year?

 

I appreciate all the responses here! According to the vehicle history report, it is listed as "2017 Toyota Prius Two" on the car history report, based on that and the pictures it doesn't seem to be the "Eco" option. I am curious, would plugging in Techstream or Torque be able to pull any DTCs (if there are any)? For example, in Torque I have a layout setup for PIIDs based on the Gen3 Prius related to Hybrid Battery readings, fan speed, etc... would this be applicable for the Gen4? I couldn't find much information on this. I also have an older version of Techstream (basically the Amazon version that comes with that generic Mongoose cable), so not sure if that version supports Gen4 readings?

 

The asking price is $10,000, which technically is already in the Blue Book range, I, however, was going to offer below that, what would be considered a "fair" price?

 

Haha, at that price range (in my area at least, as the Prius is really popular here in the Seattle area), you still see Gen 2’s with decent mileage sold at around ~$5,000, maybe you can find a Gen3 with super high mileage (250,000+ miles) at around the $6,000 range and above.

 

Just an update for anyone curious: seems like the seller (a generic used car sales lot) made a mistake on the original price, as the true price is $12,000, which at that point I just walked away since they say they are "price negotiable", but really, he just was willing to knock a few bucks. It didn't even come with the hub caps, carpet pieces, cargo cover... I tried to explain that to the salesperson + the mileage and likely needing excessive work in the near future, but they stick to "this car will run a million miles". Also whats up with these used car sales lots throwing "Touring" onto any Prius, even if it is the base package? It is super misleading and not cool.

Ironically, the same lot was selling a 2016 Prius (package 4) with only 58,000 miles for $16,500 (just $4,500 more)... lol.
