One place where “lifetime offer” actually works, and is honored. It’s with the most reviled, hated, mocked, distrusted company around: Tesla.
For years they offered lifetime free unlimited Supercharging of select makes/models. My first 2013 Tesla offered it and I went for it. Put 120K mi on car in 7 years. Never paid a dime to charge. Traded it in in 2020 for another Tesla that was one of the last to offer the deal. In 4 years, ~90K mi so far, still never paid a dime to charge.
