take care of it and run it until it dies (which would probably be around 200k, unless you take really, really good care of the chassis).
The used car market really sucks for sellers right now even on cars that hold well to resale value. I think that you would take a bath on resale and then buying another new car. Typically for people who rack up that kind of mileage you need to drive it until the wheels fall off or be prepared for high lease rates associated with the mileage.
You will be surprised how many miles you can get out of a Toyota if you take care of it, cars that are a few years old with lots of miles don’t do well on the used market, plus it’s manual so trade value will be less
If you like the car and it serves your purpose keep it
You could take it to your dealer and get an idea of what it would be worth on trade, then run the numbers to see if you want to start a new 5yr loan and keep the economy going!
