In 2019, I replaced the twenty-year-old Accord that had 256K miles with a ten-year-old Ridgeline. Now the Pilot is up around 215K miles or so and my wife is ready for something else after driving it for maybe twelve years now. Not sure when she bought it, but the kids were in car seats then and are in high school now.
The answer for CudaMan is clear: https://journal.classiccars.com/2021...-dually-wagon/
The basic Mercedes W124*, in 1984, had a .28 drag coefficient. 40 years ago. And that is a 3 box design.

Wagon mine, used for representation. I used to have a sedan but this is the one I have now. There was a sedan, coupe, cabriolet and a wagon variants of the W124.
It's all in the design.
* basic meaning only one rear view mirror on the drivers side and skinny 195/ 65R15 tires.
I’m a bit baffled by its low Cd, but that design definitely withstood the test of time very well!
On that note, check the Mythbusters episode where they compared drag on a pickup with the tailgate up vs the tailgate down....the tailgate up was more efficient
