Should I buy a new car or hold out.

My husband and I drive a 2014 and a 2015 Toyota and each have about 130k miles. They both run perfectly fine and never need repairs. We haven’t had a car payment for several years. I’m thinking of buying a new car and plan to pay it off in 3 years even though I don’t really need a new car. My thought is I don’t want to have two car payments if they both die at the same time.
