Keeping a car for 15 years sounds like the ultimate money-saving move. Once the loan disappears and the monthly payment drops to zero, every trip can feel like a tiny financial victory, but an aging vehicle can start collecting bills in other places.
That does not mean an older car automatically makes a bad financial choice. A well-maintained vehicle can deliver plenty of useful miles after its loan disappears. The catch comes when several age-related expenses start arriving together, because a car that costs almost nothing one month can suddenly demand a repair bill large enough to ruin the smug little celebration.
