    Around here the dealers will often let you take the car on an unsupervised test run. It's best to confirm when they expect it back.

    When shopping for my current car I used that 2 hour test run to drive home and show the car to my wife. :) Then I drove it up the local pass at normal freeway speeds. As expected, it was able to make the grade easily.

    Probably not worth your time.

    For the most part, what you really need to know is the remaining length of the emissions warranty that covers the hybrid components which includes the battery.

    Pretty standard practice here to have a mechanic check out a car before you buy it my understanding. Are you saying the dealership doesn't let you do that?

    Not at all- in fact I encourage the practice. Getting a car inspected by a mechanic is a very good move.

    What I'm trying to say is that there just isn't a test or a report out there that can give you a useful picture of battery health beyond "not failing today."

    ...Certainly nothing as positive or valuable as the emissions warranty and age of the car, and those details are usually easy to confirm without even being near the car.

    The mechanic's inspection (when done properly) is extremely useful to tell you about all the other parts of the car.

    The exhaust heat exchanger if it leaks can be expensive to replace. There's a way to bypass it as a cheap fix. But whether that is a good or bad idea I'm too lazy to read the discussion here... I figure i'll deal with it if or when i get there lol. Just search Prius chat.

    When i was looking for my used prime, I saw some claims early 2017's had inverter problems. Not sure how true that is and being the 1st year that was enough for me to avoid the 2017 (unless you know the person you're buying).

    2020 is when the Prime became 5 seater.

    Those were the only concerns i had buying used. So far my 2018 prime feels a lot more reliable than my 2010.

    Other random thoughts:

    - There's more cheap used primes in Montreal due Quebec's generous EV incentives, and they are easier to negotiate.
    - Toronto's insane highway speeds gonna seriously cut on your ev range. But then you can sit in traffic for hours and barely see any change in your battery level.

    Yes my plan was to go at the 2018.

    I'm just trying to look up some prius plug-in statistics so I can learn the characteristics of battery depreciation. There's 12 years of information now despite the fact that the batteries are smaller. I'm just trying to figure out if there is a drop off of range (Exponential drop which is bad)or if the depreciation continues straight-line. straight line is good because it means I never have to replace the battery, only the range will just decrease.

    sometimes lithium ion cells tend to drop off after a certain number of years but given the different complexity of how cars work, I haven't seen any hard data either wayOver this long period of time.

    I would love to see if there was a poll on the site for those who have 12-year-old batteries batteries that have 1. depreciation or
    2. replaced

    The reason why it is an important question, is I think that many people except the depreciation rather than forking out many many thousands of dollars to replace the battery if the car is old

    I think it would be helpful for all.Of course this is out the window for chemistry of the battery changed

    oldest prime is 7-8 years. plug in prius came out in 2012. reading through both forums, you will find very few battery complaints.

    If you can test drive/borrow one long enough to fully charge it, the battery capacity will give you some idea of the battery health. When new mine took a little over 6kWh on a L1 charger and around 5.8 kWh on L2. Now I'm down to somewhere in the low 5 kWhs on L2, and I don't use L1 anymore. Anything above 5 is good, and below 3kWh I'd be concerned. I'm not sure where the tipping point is where the battery starts affecting driving performance. I don't know if anyone knows because I don't think there have been many (any?) Prime battery failures yet. Although if it's bad enough you may be covered under the battery warranty.

    You'd need about 3 hours, but if you can arrange to bring it to an independent mechanic for inspection you can probably squeeze in some time to drain and charge the battery before or after that without the seller noticing.
