You can always carry enough money with you to allow you to purchase a local car if it gives out on the other side of the country.

In Sept we drove the 319k GLK350 (daily driver) from south Ga to Glacier Nat'l Park and back. We were on the way to Portland then down northern end of the PCH. We had to return early because of Helene. Other than what we came home to the trip was uneventful. I do carry a tool box with me when we travel.
