A well-packed trunk can turn a roadside headache into a minor detour.

Driving a high-mileage car isn’t always a gamble, but it definitely comes with quirks. Older vehicles often have personality—little sounds, dashboard lights with a mind of their own, and parts that work until, well, they suddenly don’t. It doesn’t mean your car’s ready for the junkyard. It just means you need to be ready when something unexpected pops up.
