My first prius was a 2006 that was gifted to me(long story) but it had not been taken care of at all. Cigarette holes in the upholstery for starters, yeah really rough, but I fell in love with that ugly thing anyway. I graduated to a 2010 with the leather heated seats and thought I was in heaven until a lady hit me 2 weeks ago and totaled it. Today I bought a 2016 and wow, just wow, driving it home I was amazed at how smooth it felt on the road compared to the gen 3 and luxurious the interior felt even though it just a 2. I bought this car with 100k miles on it because it was the only gen 4 I could afford. The guy who previously owned it drove 3 hours a day to work and back so I am hoping those miles are not as hard on it. All the recalls are up to date as well as the services. I'm going over the book now to be sure. I am one happy lady who loves her Prius!
Congratulations! The gen4 fixed the impending engine issues of the gen3. I’m sure this thing will run for many many years (if it isn’t wrecked!).
I sold our 100, 000 mile gen 2 to a Disney co-worker as I was confident that it'd last forever. It lasted until it was wrecked / hit in both front & back. Most manufacturers' cars would likely not be nearly as reliable at 100k + ... but a prius? General rule? No big deal. Congrat's !! .
Congratulations! Nice picture! With all the maintenance up-to-date, about all you might want to keep in mind would be the 12-Volt battery. It's 5-ish years old. For a traditional vehicle, that's getting old, but there's debate about 12-Volt life for the Prius. If you take trips to remote locations, battery reliability can be a factor. If you stay near to home, maybe not.
My son replaced the 12 volt on his 2005 after 8 years just to be safe. He traded the car 2 years later. The Gen 4 battery is likely different since it is now under the hood.
Another way to approach that factor is to buy a little jump pack and keep it in the corner of the glove box. If you think about it, buying a new 12 volt battery because it's 'of a certain age' is like buying a kind of insurance policy that protects you very narrowly against one risk (getting stranded because of the battery's age). Buying the little jump pack, even if we make it the same price for sake of argument, is like buying a broader insurance policy that protects you against getting stranded because of leaving a light on, unexpected electrical drain, delayed return to airport parking, six other things you haven't thought of, or the battery's age. And you can use it to bail out friends or neighbors if they need it. ... and if the day does come when the battery in the car really does flake out due to age, you can just say "yup, guess it's time", use the jump pack to solve the immediate problem, and buy a new battery then.
It's the same for many things in life, if you prepare for it, it doesn't usually happen, if you don't prepare, you can guarantee it will.
I am always pro-active re: battery replacement, since my 40 year ownership of VW/Audis. They did NOT handle low voltage well, and would shut down w/o any warning, or have bizarre electrical issues. ALL current cars are also vulnerable to spontaneous battery failure, without any warning of any kind. I resorted to replacing batteries by the calendar, every 3.5 to 4 years. NEVER went beyond 4 years. I figured a new battery ($80-160 over the years) was MUCH cheaper than the inconvenience (a failed battery is ALWAYS an inconvenience!) of being stranded with a failed battery. I'm not an electrician, but I've been told by some that a low battery will also put a strain on electronics. Just my opinion, of course.
My story is weirdly similar. Bought at 125k, from a commuter who drove about 3 hours a day. It's the nicest of the generations. It looks decades ahead of the gen 3.
