re: Credit Union Car Warranty vs Dealer Warranty

On a side note, why buy an 8-year extended warranty at purchase? Since you already have a manufacturer’s warranty of 3-5 years with the car purchase, isn’t the extended warranty just a duplicate charge for those 3-5 years and you’re paying for just the years after the original warranty expires? If you want true extended warranty, why not buy once your original expires? I don’t know and am just asking. I have never bought an extended warranty before.
