Is Owning Two Vehicles Worth It
Owning two vehicles is worth it only if both cars are actually earning their keep, not just sitting there costing you money by default.
The math changes once the cars stop being used the way they used to be
A second vehicle made sense when it filled a real need. Maybe a teenager needed to get to school and a job, or two parents needed to be in two places at once every morning. That math was simple because the cost of insuring, maintaining, and fueling the extra car was clearly less than the hassle of not having it.
Once the household shrinks, that equation often flips without anyone noticing. A car that sits in the driveway most of the week still costs money every single day, whether it moves or not. Insurance, depreciation, and upkeep don't pause just because the car isn't being driven. If nobody put a number on how often that second car actually leaves the driveway, it's worth doing now.
What changes the answer is usage, not age of the car or how long you've owned it. A second vehicle driven several days a week for errands, appointments, or work is still doing a job. A second vehicle that mostly waits for visits from adult children, or covers the rare day the first car is in the shop, is quietly becoming a cost center instead of a convenience.
There are cases where keeping two makes sense even with low use, like when one car is much cheaper to insure and acts as a backup, or when selling would net little after costs. But those are judgment calls you make once you know the real usage, not assumptions you carry forward from when the house was full.

A couple who kept both cars out of habit, not need
One household had two vehicles left after both kids moved out, a sedan one parent drove daily and an SUV that had mostly been the second teen's car. Nobody had used the SUV regularly in over a year except when a child came home and borrowed it for a weekend. The parents kept paying for registration, insurance, and upkeep on a vehicle that left the driveway a handful of times a month.
They tracked actual usage for a month before deciding anything. The sedan covered nearly all daily needs. The SUV turned out to be driven only on visits, so they sold it and arranged that visiting kids would use a rental or borrow the sedan when needed. Dropping to one vehicle cut their household's total insurance cost and removed the maintenance and depreciation they'd been absorbing on a car that wasn't pulling its weight. They kept the option open to revisit if their situation changed again.

Whether you actually need the second vehicle
If you do
If you keep both and they're genuinely used, you maintain flexibility. Errands, appointments, backup transportation, and visits from adult children are covered without scrambling. You pay for that flexibility every month in insurance and upkeep, so it only pays off if the usage is real and ongoing, not occasional.
If you don't
If you drop down to one vehicle, you lower your fixed costs immediately. Insurance, registration, and maintenance on the second car disappear. You'll need a plan for the rare day both drivers need a car at once, whether that's a rental, rideshare, or borrowing, and visiting kids will need their own arrangement too.
Once you know if the second car earns its place, compare quotes to see what keeping or dropping it costs.
Should we remove our adult child from the policy before they move out for good?
Not until they've truly stopped using your car on a regular basis, including visits. Removing a driver too early can leave gaps if they still borrow a vehicle occasionally, and some insurers treat occasional use differently than regular use. The safer approach is to wait until visits are infrequent and short, then remove them and let them get their own policy once they have steady access to a vehicle elsewhere.
If your child still visits often and drives your car for stretches of time, it may be worth keeping them listed as an occasional driver rather than removing them completely. Check with your insurer about how they classify occasional versus resident drivers, since this varies and affects both your rate and your coverage if something happens while they're behind the wheel.

Can my adult child still drive my car once they're off my policy?
Usually yes for occasional use, but coverage depends on your insurer's rules about permitted drivers. Most policies extend to someone who borrows the car with permission now and then, even if they're not listed. The risk grows if they drive regularly or keep the car at their own address, since that starts to look like they need their own policy. Check your insurer's specific definition of occasional versus regular use before assuming visits are automatically covered.
Will removing the extra car actually lower my insurance by much?
It depends on how much that car was adding versus how it's priced relative to your other vehicle. Some insurers discount multi-car households, so dropping to one car can sometimes shrink the saving you expect, since you lose that discount too. The only way to know is to get a quote for one vehicle alone and compare it to what you're paying now for both, rather than assuming the second car's listed premium is what disappears.
Is it cheaper to sell the second car or just let it sit unused?
Letting it sit rarely saves money once you account for insurance, registration, and depreciation continuing regardless of mileage. An unused car is still a car you're paying to own. Selling it frees up that money and often more, since depreciation accelerates for older vehicles anyway. The exception is if the car has very low ongoing costs and real resale value is poor enough that selling nets you very little, but that's worth confirming with an actual quote rather than assuming.
