I bought a secondary warranty that the new car dealer offered that was the same price but covers way more, like struts etc. If I sell the truck before expiry of warranty, the left over part is credited to my new vehicle.
Bought a '19 CPO Saturday, May 8th, 2021. I live in northern KY, just outside Cincinnati. Bought the truck in Dayton, OH - about 60 miles north of me. No idea if this is different in different parts of the country/world?? Current CPO coverage is 5 years/unlimited mileage from in service date.
