If you keep this car for another 5-6 years, yes. It averages about $300 a year.
However, I would't buy deal's warranty. Instead I will buy Toyota Extended Warranty. Keep in mind that regular Toyota extended powertrain warranty doesn't cover electronic device in your car except power-train related ones. You actually want to buy high-tier (costly) warranty.
The good thing is you can drop off the car at any dealership. If they need 1+ day to work on your car, you will get a free rental.
