Keep your car out of the winter salt and hot southern summer sun and you have the beginning of keeping a car that you can drive far from home indefinitely.
The next question is which car will have readily available parts after 10 years. A popular model that changes little or was produced in the same form for several years is your best bet. In addition, I prefer a car that has plenty of dealers wherever you will go such as Chevrolet or Ford.
Toyota, Honda, Suzuki and Subaru dealers are rare in small town USA.
