People have it in their head that you can "save so much money" by buying a car 1-3 years old. While it's nearly universally true that a registered vehicle will go for less money than it went for new, so many cars and trucks are made so reliably today that people regularly shop "used" thinking they are getting a better deal than they are. Keep in mind, manufacturers incentives never apply to used vehicles.
There are certain makers and models that fall much quicker than others within 1-3 years such that if you're okay with going used, you can save some coin. I think over half of BMW's new car sales now are for leases --- such that BMW shoots themselves in the foot as a constant supply of 3-year off leases are always available. But, BHs tend to gravitate around brands and models that hold their values well such that I think it's a mistake to buy said cars used.
It creates an interesting marketing dynamic for sure.
I actually do wonder how many people whom regularly buy 1-3 year old cars to save money actually price out a new, comparably equipped model --- not MSRP on a website, but with a local dealer and just get a quote. I'm not singling anybody out here, just saying that if you're going to be spending $15K+ on a used car, it's worth determining if the new versus used is worth it.
