As other people have said, it really depends on the car and model and mileage and year. Very high priced cars depreciate quickly because there is more room to drop.
Used cars sometimes don’t even drop at all if you buy it cheap. A friend of mine bought a used Acura NSX way back and sold it for more than he paid after tracking it and driving it around a few years.
That said, if you talk about “MOST” cards, buying used usually is still a better deal (as it should be), but when you bring in financing, your credit, loans, etc…
USED might make a lot of sense for a lot of people.
LEASING also isn’t as bad as people make it out to be depending on how you own/use/drive your cars and if you can deduct it for a business.
Bottom line is that the answer really depends and using a Prius as an example is pretty bad since Prius used to sell more than new since there was a shortage early on.
I personally like new myself and will probably lease (for business) our next vehicle.
