I have not seen much info about Toyota used car platinum warranty posted. The new car platinum warranty is much cheaper but I missed my chance. I was told at my dealer yesterday that the cost of a used car platinum warranty is determined by the odometer reading. In particular there is a ~$400 increase when you are above 50K miles. The next higher tier is when you are above 70K miles. Oscar (financing manager) at Carson Toyota was very helpful. I suggest giving him a call if you are in the same boat buying your lease end RAV4 EV. He says he may be able to help even if your car was purchased from another dealer.
