A retired couple in my neighborhood have five vehicles in their driveway. Two drivers. (And there may even be another one or two tucked away in their garage.) Admittedly, the RV is a great addition to their choices of fun ways to spend a summer. But some of the other vehicles overlap in function.
I realize that the initial cash value freed up by selling two might not be much. But the insurance, tax and maintenance costs for keeping that many vehicles going is significant (in my book).
Having fewer vehicles in the stable to keep track of would give an increased sense of freedom, I’d almost promise. And they would never have to move one vehicle to get to the other.
